Two new pterocarpans and a new pyrone derivative with cytotoxic activities from Ptycholobium contortum (N.E.Br.) Brummitt (Leguminosae): revised NMR assignment of mundulea lactone2016 •
Ptycholobium is a genus related to Tephrosia which comprises only three species. Compared to Tephrosia, which has been phytochemically and pharmacologically studied, Ptycholobium species have only few or no reports on their chemical constituents. Moreover, no studies on the cytotoxic activities of its secondary metabolites have been previously documented. From the non polar fractions of the roots bark of Ptycholobium contortum (syn Tephrosia contorta), two new pterocarpans: seputhecarpan C 1 and seputhecarpan D 2 and a new pyrone derivative, ptycholopyrone A 3 were isolated. Alongside, five known compounds identified as 3-α,α-dimethylallyl-4-methoxy-6-styryl-α-pyrone or mundulea lactone 4, glyasperin F 5, seputhecarpan A 6, seputheisoflavone 7 and 5-O-methyl-myo-inositol or sequoyitol 8 were also obtained. Their structures were established by the mean means of spectroscopic data in conjunction to those reported in literature. The NMR assignment of the major compound mundulea lactone...

Evaluasi Kinerja Website Pelayanan Publik Pemerintah Daerah Pada Provinsi Kalimantan TimurThis research aims to evaluate the performance of websites managed by the regional government of East Kalimantan province and also to provide input on improving the performance of websites that are considered less good. There are 9 public service websites managed by the Government of East Kalimantan including the website of the flying pesut, SIPPD, website, si website, tepra website, foreign service travel website, cooperation database application website, grant website and bansos online, regional financial transparency website, performance report website. In this research the method used is an evaluation research method that is carried out by collecting data so that it can be compared with existing standards and will then be drawn conclusions. The data collection is done by observing and reviewinglibraries, and analyzing databy using web.dev to measure performance levels, accessibility, best practices and SEO. The results of this study showed that the performance of the website had...
