This study sought to investigate the antimicrobial activity of sixBackground: plants used in traditional medicine in Africa. The antimicrobial activity of the six medicinal plant extracts (aqueousMethods: and ethanol) were evaluated against (ATCC 21784), Proteus mirabilis (ATCC27856) were using thePseudomonas aeruginosa Aspergillus fumigatus agar-well diffusion protocol. The activities of these extracts were compared with the positive controls chloramphenicol and griseofulvin. Similarly, the phytochemicals from the extracts were qualitatively assayed and their percentage yield calculated by standard methods. The bacterial organisms used, and , wereResults: P. mirabilis P. aeruginosa slightly-to-highly susceptible to aqueous and ethanolic extracts from the various test plants, while was insensitive to the treatments. The ethanolic A. fumigatus extracts of the sampled plants showed superior inhibitory performance on the target bacteria to the aqueous extracts. Aqueous and eth...
Three ethnomedicinal plants namely, Alstoniamacrophylla (AM),Mallotus peltatus (MP) and Ophirrhoza nicobarica (ON) of Little Andaman Islands were investigated for antiinfective, anti-inflammatory, antipyretic and antioxidant activities, based on their tribal use. The stem bark, leaves or whole herbwere extracted inwater andmethanol. In vitro and in vivo toxicity was determined in vero andHep-2 cells and in animalmodels. Antibacterial and antifungal sensitivity was tested by agar dilution method while the antiviral activity was determined by plaque reduction assay against Polioviruses and Herpes simplex viruses. The anti-inflammatory activities were tested in carrageenan and dextran induced paw oedema and cotton pellet-induced granuloma and antipyretic activity by yeast-induced pyrexia in Wister rats. The antioxidative property was determined by free radical scavenging and DNA cleavage tests. The methanol extract of ONwas found to be non-toxic upto 3000 mg ml-1 concentrationwhileAMandMP leaf extracts are non-toxic upto 3.2 gm kg-1 body weight of rats. At 300 mg ml-1 dose ON extract completely inhibits plaque formation in HSV 1 and HSV 2; while the eclipse phase initiation was delayed at 100 mg ml-1. Themethanol extract of MP and AM showed antibacterial activity at 128-2000 and 64-1000 μg ml-1 concentrations against 151 and 167 bacterial isolates respectively. The antifungal activity of AM leaf extract at 16-128 mg ml-1 concentration was limited against Trichophyton rubrum, T.mentagrophytes andMicrosporum gypseum. The extract of AM and MP leaf at 200-400 mg kg-1 p.o. revealed significant dose dependent anti-inflammatory activity in carrageenan and dextran-induced paw oedema, and in cotton pellet-induced granuloma in rats compared to indomethacin (10 mg kg-1). Both the extracts at 200-300 mg kg-1 showed significant antipyretic activity compared to paracetamol (150 mg kg-1). A dose-dependent free radical scavenging activity and a protective effect on DNA cleavage induced by H2O2 and UV-photolysis was observed with both the extract. All these data are highly significant (p < 0.05) compared to the control. The bioactive fractions of ON, AM and MP showed the presence of alkaloids, flavonoid and b-sitosterol respectively. The in vitro and in vivo results justify the use of these ethnomedicines in primary health care. Further investigation is required to know the exact mechanismof action.

For millions of years, plants were utilized to store food, to treat health conditions, and to cure infection like epidemics. Over the ages the awareness of their medicinal benefits has been conveyed within and amongst human cultures. Actually, data on various plants' antimicrobial activity, so far assumed empirical, have been clinically verified, along with the growing amount of studies on antimicrobial-resistant pathogenic microorganisms. Materials obtained from natural can potentially suppress bacterial growth in various circumstances and in the particular associated with disease treatment, numerous researches have been done to identify the chemical structure of these plant antimicrobial agents and the mechanisms engaged in bacterial inhibitory effect, whether separately or in conjunction with conventional antimicrobials. Thus, herbal medicines with focus on their antibacterial properties will be investigated in the present study.

SCREENING OF SOME MEDICINAL PLANTS FOR THEIR ANTIMICROBIAL ACTIVITIES Original ArticleObjective: Our objective of this research work was to investigate antimicrobial activity of five species of traditionally used medicinal plants namely Adhatoda vasica, Artemisia annua, Cordia oblique, Croton bonplandianum and Euphorbia milli against different strains of bacteria and fungi which are known to cause various types of infectious diseases. Methods: Organic extracts of these plants leaves (dry) were prepared, and antimicrobial sensitivity of these organic extracts (Hexane, chloroform, acetone, and methanol) against selected bacterial and fungal strains were performed by disc diffusion assay method and Resazurin-based Microtitre Dilution Assay method. Results: Among these plants, Cordia oblique (chloroform extract) and Croton bonplandianum (Hexane extract), which showed superior antimicrobial activity in the primary screening test. Croton bonplandianum showed the maximum yield (7.3%) and Adhatoda vasica showed minimum yield (0.57) of plant extract. Chloroform extracts of Cordia oblique and hexane extract of Croton bonplandianum showed very good antimicrobial activity (MIC 0.37 mg/ml) against Staphylococcus aureus and Klebsiella pneumoniae. With this Artemisia annua (chloroform extract) showed very remarkable antifungal activity (MIC 0.37 mg/ml) against Aspergillus niger. Among the different fractions (Hexane, chloroform, acetone and methanol) tested for antimicrobial activity, the non-polar fractions were more active than the polar fractions. Conclusion: In this study all the tested plants Adhatoda vasica, Artemisia annua, Cordia oblique, Croton bonplandianum and Euphorbia milli showed antimicrobial activity against at least one strain of bacterium and fungus. This might justify their claimed uses in the treatment of various infectious diseases.

Anti-microbial Properties of Selected Plant Leaf Extracts Against Aspergillus niger (van Tieghem), Pseudomonas aeruginosa (Schroeter) and Staphylococcus aureus (Rosenbach)2021 •
With growing reports of multidrug-resistant pathogens causing untreatable human infections, the need for new antimicrobial therapies is becoming increasingly important. This study was conducted to investigate the antimicrobial properties of the leaf extracts of Premna odorata Blanco, Petersianthus quadrialatus Merr., Shorea astylosa Foxw., and Tridax procumbens Linn. The medicinal importance of these plants remains understudied despite their abundant distribution and endemism in the Philippines. A disk diffusion assay was utilized to test the antimicrobial properties of T. procumbens leaf extract against Pseudomonas aeruginosa and Staphylococcus aureus. On the one hand, the fungal colony and spore germination assay was used to test P. odorata, P. quadrialatus, and S. astylosa leaf extracts against Aspergillus niger. Different concentrations of leaf extracts were prepared and compared with positive and negative controls. T. procumbens minimally inhibits the growth of P. aeruginosa (10 mm) and S. aureus (10 mm), while S. astylosa leaf extracts revealed the most significant inhibition on colony growth (5.38 mm) and spore germination (15). P. odorata and P. quadrialatus showed the least (28.35 mm; 82.17) and moderate (10.97 mm; 49.5) inhibitory potentials, respectively. The discovery of new antimicrobial compounds from these plant extracts is seen as a potential resolve to the pressing problem of antimicrobial resistance.
