Chemical Composition of Euphorbia Hirta L. collected in Dan Phuong, Hanoi
During the screening for biological active compounds from the medicinal plant, a species of Euphorbia hirta L. collected from Dan Phuong-Hanoi was utilized for its phytochemical study. From the n-butanol extract, eight compounds, including nonacosan-1-ol (1); β-sitosterol (2); β-sitosterol glucoside (3); quercetin (4); nicotiflorin (5); rutin (6); afzelin (7) and quercitrin (8) have been isolated. Their structures were determined by analysis of IR, MS and NMR (1D and 2D) spectroscopy as well as by comparison with published data.
