SOME GLYCOSIDES ISOLATED FROM DESMODIUM GANGETICUM (L.) DC. OF VIET NAM

Le Minh Ha

Abstract


From the methanol extract of the leaves of Desmodium gangeticum collected in Me Linh, Ha Noi, we isolated 5 compounds. In which, there are four glycosides including (6S,9R)-roseoside (1), kaempferol-3-O-rutinoside (nicotiflorin) (2),  quercetin-3-O-rutinoside (rutin) (3), β-sitosterol-3-O- β-D-glucopyranoside (4), and the other is protocatechuic acid (5). Kaempferol-3-O-rutinoside (2) was isolated from Desmodium gangeticum for the first time while (6S,9R)-roseoside (1) was isolated from the genus Desmodium for the first time. Their structures were determined by 1D and 2D NMR spectra.
