Chemical constituents from n-hexane and ethyl acetate extracts of Euphorbia hirta L. grown in Vietnam

Abstract

Abstract The medicinal plant Euphorbia hirta L. has been widely acknowledged for use in traditional medicine of Vietnam. The whole plants of E. hirta are commonly applied to cure a wide range of diseases, especially gastrointestinal disorders, skin problems, and respiratory system. This study focused on chemical composition of the E. hirta L. whole plant. The chemical investigation of n-hexane and ethyl acetate extracts of this species led to the isolation and structural determination of taraxerol (1), campesterol (2), astragalin (3), hymenoxin (4), luteolin-7-O-β-D-glucopyranoside (5) and quercetin 3-O-α-L arabinofuranoside (6) by spectroscopic methods including 1D-NMR, 2D-NMR, IR, HR-MS in combination with published literature.
