Chemical constituents from n-hexane and ethyl acetate extracts of Euphorbia hirta L. grown in Vietnam. Issue 2 (January 2020) - Bach, Le Thi
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.
