Abstract<br />

Introduction<br />

The plants of genus Tephrosia of family Leguminosae are widely distributed in<br />

many tropical and subtropical countries of the world and have been used in folk<br />

medicine for the treatment of large number of diseases. The importance of this genus<br />

is similar to that of other therapeutically renowned genera. This review includes<br />

the chemical studies on different species mainly the isolation and identification of<br />

flavonoids, rotenoids and study of activity of some isolated compounds and also<br />

includes diffe-rent pharmacological activities like antioxidant, antimicrobial, anticancer,<br />

antiplas-modial, anti-inflammatory, larvicidal and toxicity studies of extracts<br />

and fractions.<br />

Keywords: Tephrosia; Flavonoids; Rotenoids; Phytochemistry; Pharmacology;<br />

Acivity.<br />

Plants have been used for the treatment of diseases from centuries. Natural product<br />

chemistry, especially phytochemistry, has become a topic of interest for most of the researchhers<br />

due to the advantages of the plant derived medicinal compounds over the traditional<br />

ways of using herbal plants. Ethnopharmacology plays an important role in the discovery of<br />

new biologically active compounds. The process usually starts with searching of useful<br />

plants from different records to the development of methods for the industrial production of<br />

drugs (Rout et al., 2009; Farnsworth et al., 1985; Koehn and Carter, 2005). According to<br />

World Health Organization (WHO) more than 80% of the world’s population uses plants for<br />

the treatment of their diseases (Calixto et al., 1998; Duraipandiyan et al., 2006).<br />

The genus Tephrosia belongs to the family Leguminosae and subfamily Papilionaceae.<br />

There are approximately 400 species included in this genus. The plants in this genus are<br />

widely distributed in tropical, sub-tropical and arid regions of the world (Willis, 1973; Al-<br />

Zahrani, 2007). The plants are prostate or erect herbs or in the form of soft or woody shrubs<br />

(Hacker, 1990). The base chromosome number of this genus is X=11 and are placed in the<br />

tribe Galegeae of the family Leguminosae (Atchison, 1951; Agarwal and Gupta 1983). Many<br />

plants from this genus have been used traditionally for the treatment of diseases like rheumatic<br />

pains, syphilis, dropsy, stomach ache, diarrhea, asthma, abortifacient, respiratory disorderrs,<br />

laxative, diuretic, and inflammation etc (Qureshi et al., 2010; Dzenda et al., 2007). Tephrosia<br />

purpurea, an important plnt of the genus is used as tonic, laxative, antivenom, antiulcer,<br />

antidiarhheal, and in leprosy (Virupanagouda et al., 2011).<br />

The main purpose of this review is to provide a comprehensive and up-to-date knowledge<br />

of the pharmacological and phytochemical research work performed on the genus Tephrosia.<br />

The plants of this genus have a large potential for study of its activities and chemical<br />

constituents for important leads.<br />

Chemical constituents from plants of genus Tephrosia<br />

A great variety of plants belonging to genus Tephrosia have been studied for their<br />

chemical constituents and pharmacological activities. The number of species studied phytochemically<br />

are much more than those studied pharmacologically. Different classes of organic<br />

compounds have been isolated of which some have been tested for their biological activities<br />

and some still unknown for their effect. The main classes of compounds include flavonoids,<br />

rotenoids, terpenoids, and sterols. It should be noted that flavonoids are the most abundantly<br />

isolated and identified compounds in the genus. Similarly in case of essential oil and fixed<br />

oil, we can see that very little work has been done by the scientists. Tephrosia purpurea, Tephrosia<br />

toxicaria, Tephrosia candida, Tephrosia elata, and Tephrosia villosa have been the<br />

plants of interest for the scientists. The readers will also find some work on the stereochemistry<br />

of compounds. Praecansone A, flavonoid from Tephrosia pumila for example, exists<br />

in the form of two isomers (Dagne et al., 2012).<br />

Table 1 briefly describes all the chemical work done on genus Tephrosia. Readers will<br />

see some novel compounds as well some compounds repeating in many species. Some<br />

chemicals in the table would be familiar to us as they have been isolated from other genera as<br />

well<br />

Some of the compounds isolated have been studied for their pharmacological actions (see<br />

table 2). The activities reported include anticancer, antiplasmodial, larvicidal, and others. There<br />

are many compounds in Table 1 whose activities are not studied under the genus Tephrosia<br />

but if we look into the literature, we find their presence in other genera and their activities<br />

determined for example Pseudosemiglabrin, Flemichapparin, Caryophyllene oxide, deguelin,<br />

pongamol, lupeol, possess platelet aggregation antagonism, antifungal, antifungal, anticancer,<br />

anticonvusant, and antiinflammatory respectively (Pirrung and Lee, 1995; Gahlot et al.,<br />

2012; Yang et al., 2000; Udeani et al., 1997; Basu et al., 1994; Geetha and Varalakshmi,<br />

2001). Caffeic acid and rutin, which are also found in Phyllanthus sellowianus have analgesic<br />

activity (Calixto et al., 1998).<br />

It can be concluded from the above discussion that if, for example, any species of<br />

genus Tephrosia having rutin or caffeic acid as its major component, is not reported for analgesic<br />

activity, may possess it. So in this way this methodology can give us a hint or base, which<br />

study to be carried on plant.<br />

Pharmacological profile of plants from genus Tephrosia<br />

Several plants of the genus have studied for their medicinal and therapeutic potential.<br />

A brief description of the work done so far is given below:<br />

Antioxidant activity<br />

Only a few species of Genus Tephrosia have been studied for their antioxidant activity.<br />

In 2007, G.P. Choudhary studied the ethanolic extract of Tephrosia purpurea for its antioxidant<br />

activity (Choudhary, 2007). The aqueous extract of the whole plant of Tephrosia<br />

purpurea also showed free radical scavenging activity in DPPH test (Gunjegaonkar et al.,<br />

2010). From Tephrosia egregia the ethyl acetate and methanol extracts showed high antioxidant<br />

activities (Arriaga et al., 2009a). Obovatin, a flavonoid present in Tephrosia toxicaria<br />

showed significant antioxidant acivity of IC50 3.370 μg/mL. It was also seen that the methanol<br />

fraction of the ethanol extract from roots had the highest antioxidant activity (Vasconcelos<br />

et al., 2009). Tephrosia villosa also possess antioxidant activity due to the presence of<br />

20(29)-lupen-3-one, a compound also identified in Daedaleopsis tricolor where it inhibited<br />

lipid peroxidation by 6.4% (Prashant and Krupadanam 1993; Kim et al., 2001). The ethanol<br />

Phytopharmacology 2013, 4(3), 598-637 Touqeer et al.<br />

ether extract of Tephrosia vogelii seeds also showed antioxidant and free radical scavenging<br />

activity (Li et al., 2010).<br />

Antibacterial activity<br />

The species from Genus Tephrosia have also been studied for their antibacterial activity.<br />

Tephrosia vogelii was found to possess antimicrobial activity (Wanga et al., 2007). The<br />

dichloromethane extract from the roots and leaves was tested against S. aureus, E. coli and F.<br />

phoseolida. Hu et al., in 2011 also studied the antimicrobial and bactereostatic activity of<br />

ethanol and aqueous extract from Tephrosia vogelii seeds on E. coli, S. aureus and S. paratyphi<br />

B. and proved the antibacterial efficacy of the plant to be significant at high doses (Hu et<br />

al., 2011). The root extract of Tephrosia villosa showed moderate antibacterial and anti<br />

fungal activity (Ganapaty et al., 2008a). In another study on Tephrosia villosa the fruit, leaf,<br />

and root extract showed activity against C.neoformans, E.coli and B.anthracis respectively.<br />

The ethanolic twig extract was most active against C.neoformans and S.typhi (Nondo et al.,<br />

2011). In case of Tephrosia purpurea, studies have been made on the antimicrobial activity<br />

of methanolic extract of Tephrosia purpurea roots on B. subtilis, S. aureus, M. luteus, the<br />

gram positive bacteria and the gram negative including E. coli, P. aeruginosa, and S. typhimurium<br />

(Gupta et al., 2008). In another study on Tephrosia purpurea, the roots showed antimicrobial<br />

activity against P. aeruginosa and no activity against S. aureus and E.coli (BNLD<br />

Rangama et al., 2009). Chinniah et al., in 2009 and Annalakshmi et al., in 2009 proved<br />

Tephrosia purpurea to have marked activity against H. pylori, an agent responsible for GIT<br />

ulcers (Chinniah et al., 2009; Annalakshmi et al., 2009). The methanolic leaf extract from<br />

Tephrosia tinctoria showed activity against B. subtilis, S. marceseans, and low activity for B.<br />

cereus and P. aeuriginosa (Ganapaty et al., 2010). Tephrosia deflexa and its isolated compounds<br />

were studied for antibacterial activity (Kare et al., 2006). The antibacterial activity of<br />

Tephrosia linearis has also been reported (Ratsimamanga et al., 1994).<br />

Antifungal activity<br />

In our literature survey, we found less work on antifungal activity of species from Genus<br />

Tephrosia. Only three species are known to possess antifungal potential. The methanolic<br />

extract of Tephrosia purpurea showed significant activity against A. niger and C. albicans<br />

(Gupta et al., 2008). Tephrosia hildebrandtii showed antifungal activity against C.cucumerinum.<br />

The activity was found to be related to a chemical compound isolated from its roots<br />

(see table 2) (Lwande et al., 1985b). Tephrosia tinctoria also showed activity against A.<br />

niger, C. albicans. The methanolic extract was found to be more active against the aforementioned<br />

organisms. However the methanolic extract showed no activity against S. cerevisiae<br />

(Ganapaty et al., 2010).<br />

Antiprotozoal and anti plasmodial activity<br />

Extract from the seed pods of Tephrosia elata showed antiplasmodial activity (Muiva<br />

et al., 2009; Muiva, 2012). Flavonoid extracted from the roots of Tephrosia pumila also showed<br />

activity against L. donovani, T. b. rhodesiense and T. cruzi (Ganapaty et al., 2008b).<br />

Isolated flavonoids from the root of Tephrosia tinctoria were studied for antiprotozoal and<br />

623<br />

Phytopharmacology 2013, 4(3), 598-637 Touqeer et al.<br />

antiplasmodial activities against T. b. rhodesiense, T. cruzi, L. donovani, and P. falciparum<br />

(Ganapaty et al., 2009a). Ganapaty, also studied the antiprotozoal activity of three Tephrosia<br />

species, namely, T. pulcherrima, T. pumila, and T. calophylla on Leishmania, Trypanosoma<br />

and Plasmodium parasites (Ganapaty et al., 2009c). Chloroquine sensitive and chloroquine<br />

resistant strains of P. falciparum were inhibited by the extracts from the stem of Tephrosia<br />

purpurea with IC50 values of 10.47 ± 2.22 μg/ml and 12.06 ± 2.54 μg/ml, respectively (Juma<br />

et al., 2011). Tephrosia purpurea has also been studied for antileishmanial activity in hamsters<br />

and Indian langular monkeys infected by L. donovani (Sharma et al., 2003).<br />

Anti pyretic and Anti inflammatory activity<br />

In 2010, Sandhya et al., studied the anti inflammatory activity of two species of Tephrosia<br />

namely Tephrosia maxima and Tephrosia purpurea by HRBC membrane stabilizing<br />

method. Both plants showed almost equal activity at doses of 500ug/ml. Tephrosia maxima<br />

giving 79.49% and Tephrosia purpurea giving 79.01% protection (Sandhya et al., 2010).<br />

Another study on Tephrosia purpurea root extracts showed its antipyretic and anti inflammatory<br />

activity (Valli et al., 2011). The methanolic extract of Tephrosia vogelii showed significant<br />

analgesic and anti-inflammatory activity in mice and rats using hot plate method and egg<br />

albumin induced oedema respectively (Adaudi et al., 2009). The root extract of Tephrosia<br />

sinapou showed to possess significant anti-inflammatory activity. The extract reduced inflammatory<br />

leukocyte recruitment, oxidative stress and other parameters involved directly or<br />

indirectly to the process of inflammation (Martinez et al., 2012). Tephrosia spinosa also showed<br />

anti inflammatory activity in an experimental model of carrageenin induced paw edema.<br />

The standard drug used was indomethacin (Chakradhar et al., 2005). The antipyretic activity<br />

of Tephrosia bracteolata has also been reported (Onaolapo et al., 2009).<br />

Anticancer and cytotoxic activity<br />

Cytotoxicity of some chemical compounds found in Tephrosia calophylla and Tephrosia<br />

candida have been studied using different cell lines (Ganapaty et al., 2009a; Ganapaty et<br />

al., 2009b; Roy et al., 1986; Parmar et al., 1988). The cytotoxicity of Tephrosia pulcherrima<br />

and Tephrosia pumila has also been studied by Ganapaty et al., in 2009 using HT-29 and<br />

RAW cell lines (Ganapaty et al., 2009c). In 2011 Kishore et al., mentioned Tephrosia purpurea<br />

containing an important chemical, B-sitosteol having anticancer and cancer protective<br />

activities against prostatic, breast and colonic carcinomas. In addition to the aforementioned<br />

activities of B-sitosterol, it is also an antioxidant and has significant effect on hypercholesterolemia<br />

and BPH (Kishore and Roy, 2011). In another study the anticarcinogenic activity<br />

of Tephrosia purpurea extract was tested in an experimental model of hepatocarcinoma in<br />

rats. The extract showed significant cancer chemoprevention (Hussain et al., 2012). Shanmugapriya<br />

et al., also studied the anticarcinogenic potential of Tephrosia purpurea in HELA<br />

cervical cancerous cell line. Different extracts were tested out of which ethyl acetate<br />

produced the most potent effect (Shanmugapriya et al., 2011). In a study by Subhadra, three<br />

species namely, Tephrosia calophylla, Tephrosia maxima and Tephrosia purpurea showed<br />

significant cytotoxic activity out of which Tephrosia calophylla showed the maximum activity<br />

(Subhadra et al., 2011). The ethanolic fruit and root extract of Tephrosia villosa showed<br />

toxicity to brine shrimp whereas the extract from leaves and twigs was found to be non toxic<br />

(Nondo et al., 2011). The ethyl acetate extract from stems of Tephrosia toxicaria possess<br />

624<br />

Phytopharmacology 2013, 4(3), 598-637 Touqeer et al.<br />

flavonoids having cancer chemopreventive activities (Jang et al., 2003). The flavonoids extracted<br />

from Tephrosia tinctoria possess cytotoxic activity tested in Cell line L-6 (Rat skeletal<br />

muscle myoblasts) (Ganapaty et al., 2009a). Tephrosia calophylla was also found to possess<br />

anticancer activity. The root extract inhibited growth and induced apoptosis in the human breast<br />

carcinoma (Adinarayana et al., 2009). Tephrosia vogelii root and leaf extract was found<br />

to be toxic to brine shrimps at doses of LC50: 0.960; 0.958 μg/ml, respectively (Wanga et al.,<br />

2007).<br />

Hepatoprotective activity<br />

In 2011, Shah et al., studied the hepatoprotective effect of Tephrosia purpurea in<br />

CCl4 induced hepatotoxicity in rats. The ethyl acetate fraction at doses of 50mg/kg was found<br />

to be effective and comparable to silymarin (Rajal Shah et al., 2011). The hepatoprotective<br />

effect of Tephrosia calophylla has also been reported (Adinarayana et al., 2011).<br />

Animal feed<br />

In an effort to find new and cheap sources of food for animals, several species of genus<br />

Tephrosia have been studied. The nutritive value of three species of Tephrosia, namely,<br />

Tephrosia candida, Tephrosia bracteolata, and Tephrosia linearis have been studied (Babayemi<br />

et al., 2003). According to Babayemi and Bamikole, a mixture of Tephrosia candida<br />

leaves and guinea grass can serve as a good animal feed. The mixture has an additional benefit<br />

of low methane production upon fermentation (Babayemi and Bamikole. 2006b). Tephrosia<br />

bracteolata can serve as a good diet in laying hens both from nutritive and economic<br />

aspect (Akande et al., 2008). Tephrosia vogelii, Tephrosia candida, and Tephrosia purpurea<br />

can also be a good addition in the diet of ruminants (Mbomi et al., 2011). The use of Tephrosia<br />

candida and Tephrosia bracteolata in goats has also been established (Babayemi and<br />

Bamikole 2006a). A study on Tephrosia candida seeds has also been reported (Babayemi and<br />

Bamikole 2007).<br />

Larvicidal, insecticidal and antifeedant activity<br />

Different species from the genus have been studied for larvicidal, insecticidal, and<br />

antifeedant activities. There is an extensive work on the study of Tephrosia as an agent to<br />

control the population of insects harmful to animals and plants.<br />

The hexane extract from Tephrosia egregia showed potent larvicidal activity against<br />

aedes aegypti (Arriaga et al., 2009a). The whole plant extract of Tephrosia purpurea was tested<br />

for its larvicidal activity against the larvae of Culex quinquefasiciatus. The extract showed<br />

100% mortality in very small doses suggesting its beneficial use in controlling the mosquito<br />

reproduction (Deepak Kumar et al., 2012). The extracts of Tephrosia vogelii also possess<br />

larvicidal activity and therefore can be used to control mosquitoes (Matovu and Olila. 2007).<br />

The ethanolic extract of roots, leaves, fruit and twigs of Tephrosia villosa showed significant<br />

activity against C. quinquefasciatus larvae (Nondo et al., 2011). The ethanol extract from<br />

roots, stems, leaves, and pods and some fractions of Tephrosia toxicaria were tested for lavicidal<br />

activity with the larvae of Aedes aegypti. The ethanolic root extract, hexane and chlor-<br />

625<br />

oform fractions had (LC50 47.86 ppm) (LC50 23.99 ppm) and (LC50 13.80 ppm) respectively<br />

(Vasconcelos et al., 2009). Tephrosia nyikensis have been reported to possess larvicidal<br />

activity on Anopheles mosquito’s larvae (Wanjala et al., 2006). The oil obtained from Tephrosia<br />

cinerea showed larvicidal activity against Aedes aegypti larvae (Arriaga et al., 2008).<br />

The chloroform and methanol extracts of Tephrosia nubica were tested against Spodoptera<br />

littoralis and Agrotis ipsilon. The population of the pests was reduced due to the effect of the<br />

extract on all the stages of growth (Sharaby and Ammar, 1997). Tephrosia vogelii leaf extract<br />

was found to be effective in controlling ticks, an important insect and ectoparasite (Gadzirayi<br />

et al., 2010). Tephrosia magropoda is also reported to have insecticidal properties (Tatteksfield<br />

and Gimingham, 1932). In 2012, Kalume et al., reported the acaricidal activity of leaf<br />

extracts of Tephrosia vogelii on tick Rhipicephalus appendiculatus and mentioned its advantage<br />

of being economical than synthetic compounds (Kalume et al., 2012). The insecticidal<br />

property of Tephrosia purpurea whole plant was tested against Callosobruchus maculates,<br />

the pest on Phaseolus mungo (Diwan and Saxena, 2010). In 1992, Kole et al., isolated a<br />

rotenoid, amorpholone from Tephrosia candida having potent insecticidal properties (Kole et<br />

al., 1992). Tephrosia elata showed significant antifeedant activity against M. testulalis, S.<br />

exempta and E. sacchariana. The antifeedant activity is attributed to the presence of rotenoid<br />

compounds (Bentley et al., 1987). The larvicidal activity from seed pods of Tephrosia elata<br />

and Tephrosia aequilata has also been studied by Muiva, against the larvae of Aedes aegypti<br />

(Muiva, 2012). Antifeedant activity of flavonoids from Tephrosia emoroides was tested<br />

against Chilo partellus, a very destructive pest of maize. Emoroidenone, a flavonoid isolated<br />

showed strong feeding deterrence of 66.1% against the larvae at a dose of 100 μg (Machocho<br />

et al., 1995). The roots of Tephrosia hidebrandtii also possess antifeedant activity against the<br />

pest, Maruca testulalis (Lwande et al., 1985).<br />

Antidiabetic activity<br />

The aqueous seed extract of Tephrosia purpurea showed significant antihyperglycemic<br />

activity in streptozotocin induced diabetic rats (Pavana et al., 2009). The ethanolic extract<br />

of from Tephrosia villosa leaves showed reduction in glucose level and pancreatic cell<br />

regeneration in alloxan induced diabetes in rats (Ahmad et al., 2009). Balakrishnan et al.,<br />

also repoted antidiabetic activity of extract from root of Tephrosia villosa (Balakrishnan et<br />

al., 2007).<br />

GIT activity<br />

Tephrosia vogelii leaf extract exerted a stimulant effect on the GIT smooth muscles.<br />

This was demonstrated by the contraction of the ileum isolated from guinea pig hence showing<br />

the purgative property of the plant (Dzenda et al., 2008b). Aqueous extract of Tephrosia<br />

purpurea root showed gastric ulcer healing and cytoprotective activities (Deshpande and<br />

Shah 2008). The extract of Tephrosia calophylla leaves showed significant antiulcer and cytoprotective<br />

activity at doses of 50mg/kg and 100mg/kg (Divya, et al., 2011).<br />

Antihyperlipidemic effect<br />

The antihyperlipidemic effect of Tephrosia calophylla has been studied in wistar albino<br />

rats (Mohan, 2011). The leaf extract of Tephrosia purpurea showed antihyperlipi-demic<br />

activity in an experimental model of diabetic rats (Pavana et al., 2007). Akhtar et al., also<br />

studied Tephrosia purpurea for the same purpose and found a significant reduction in all the<br />

parameters (Akthar et al., 2011).<br />

Toxicity<br />

Tephrosia purpurea extract was evaluated by Talib et al., in 2012 for its toxicity in<br />

rodents. A dose up to 2000mg/kg was well tolerated in the acute toxicity studies whereas in<br />

sub acute toxicity studies, a dose 200mr/kg and 400 mg/kg showed no significant change in<br />

any of the parameters thus concluding that the plant is safe for use in treatment of different<br />

diseases (Talib Hussain et al., 2012). Tephrosia toxicaria used as a fish poison was studied<br />

by Clark in 1930. A compound, Toxicarol was identified as the major component (Clark,<br />

1930). The toxicity of Tephrosia vogelii was reported on mice. The signs were similar to<br />

those associated with the toxicity from rotenone. The LD50 of leaf extract calculated was<br />

134.16 mg/kg (Dzenda et al., 2008a). The chloroform extract of Tephrosia tinctoria leaves<br />

exhibited significant piscicidal activity compared to methanolic extract in gold fish (Ganapaty<br />

et al., 2010). Toxic hepatopathy was reported in sheep grazing on Tephrosia cinerea. The<br />

disease was also experimentally induced in the sheep in order to confirm the results (Santos<br />

et al., 2007). Tephrosia apollinea was also found to be toxic in a study on goats (Suliman et<br />

al., 1982). The toxicity of Tephrosia bracteolata has also been studied (Onaolapo et al.,<br />

2009). In a study on mice Cai et al., found Tephrosia candida to be safe and no significant<br />

signs of toxicity were observed (Cai et al., 2010).<br />

Miscellaneous activities<br />

The root extract of Tephrosia purpurea showed xanthine oxidase inhibitory activity<br />

compare with standard, Allopurinol (Nile and Khobragade, 2011). Patel et al., studied the effect<br />

of Tephrosia purpuria on polycystic ovary syndrome (PCOS) in rats. (PCOS) was induced<br />

by the administration of Letrozole. The dried seed powder given orally showed normalization<br />

in the estrous cycle and reduction in the weight of the reproductive system as well as<br />

of the ovary (Patel and Thakor, 2012). Kumar et al., found Tephrosia purpuria to be effective<br />

anxiolytic agent and comparable to the standard drug, Diazepam. The hydroalcoholic extract<br />

at a dose of 200mg/kg and 400mg/kg orally was administered to mice in different maze models<br />

in the study (Kumar, et al., 2011). The acetylcholinesterase inhibitory activity of Tephrosia<br />

purpurea and neurobehavioral studies were made on zebra fish, a model for the study of<br />

neurodegenerative activities (Kannan and Vincent, 2012). Tephrosia purpurea has also been<br />

proved for its antiepileptic effect (Asuntha et al., 2010). Lodhi et al., studied the flavonoidal<br />

extract of Tephrosia purpurea and proved its potential for healing burn wounds. This activity<br />

is supposed to be due to its free radical scavenging property (Lodhi et al., 2010). The anti<br />

allergic effect of Tephrosia purpurea has been reported (Gokhale and Saraf 2000). The<br />

extract of Tephrosia purpurea stabilized mast cells significantly showing its usefulness in the<br />

treatment and management of asthma (Gajera Paresh Lallubhai and Dalal Mittal, 2011). In<br />

another study Tephrosia purpurea showed spasmolytic activity in the trachea of guinea pigs<br />

thus strengthening the view of its use in asthma (Soni et al., 2004). Tephrosia purpurea has<br />

also been studied for its immunomodulatory effect (Damre et al., 2003). Ashokkumar et al.,<br />

studied the diuretic activity of methanol extract of Tephrosia purpurea (Ashokkumar et al.,<br />

2012). The aqueous extract from roots of Tephrosia purpurea also posses antilithiatic activity<br />

Phytopharmacology 2013, 4(3), 598-637 Touqeer et al.<br />

(Swathi et al., 2008). Still another study was made on the Tephrosia purpurea leaves for its<br />

protective and curative ability for renal injury in rats (Jain and Singhai, 2009). Study on<br />

chemical constituents of Tephrosia candida revealed a sesquiterpene having significant estrogenic<br />

activtity (Hegazy et al., 2011). The chloroform and methanolic extract of Tephrosia<br />

spinosa showed significant ant helmintic activity against earth worms (Pheretima posthuma)<br />

(Ilango et al., 2011). The leaf extract of Tephrosia vogelii was found to possess significant<br />

anthelmintic activity against Ascaridia galli, a parasite in chicken (Siamba et al., 2007). The<br />

methanol extract of Tephrosia vogelii produced significant reduction in the blood pressure of<br />

cats (Adaudi et al., 2009).<br />

Conclusion and discussion<br />

The plants of genus Tephrosia are of high therapeutic importance. We can see that a<br />

large number of species are studied for their chemical constituents but the number of isolated<br />

compounds from individual specie is very few with some exceptions. Mostly studied compounds<br />

include flavonoids and rotenoids. Studies on oil composition are very less. The genus<br />

has significant anticancer and larvicidal potential.<br />
