Summary
Inositol, Megastigmanes and Flavonoids from the Leaves of Bauhinia variegata in Vietnam
The leaves of Bauhinia variegata (Ban trang) were collected in Dien Bien province and were used to study the chemical composition. From the n-BuOH fraction, five compounds were isolated including pinitol (1), (9S)-9-hydroxymegastigma-4,7-dien-3-one 9-O-β-D-glucopyranoside (2), (9S)-roseoside (3), rutin (4), and tamarixetin 3-robinobioside (5). Their structures were determined through analysis of NMR and MS spectral data in comparison with those published in the literatures. Notably, these substances were isolated for the first time from Bauhinia variegata in Vietnam.
