PHYTOCHEMICAL STUDIES ON EUPHORBIA HYPERICIFOLIA

Ten compounds have been isolated from the roots of Euphorbia hypericifolia viz., β -sitosterol (EH-1), β-sitosterol-3-O- β -D-glucopyranoside (EH-2), ursolic acid(EH-3), oleanolic acid (EH-4), 16α-hydroxy-ent-kauran-19-oic acid (EH-5) , 16α, 17-dihydroxy-ent-kauran-19-oic acid (EH-6) , ent-kaur-15-en-19-oic acid (EH-7), ent-kaur-15-en-17-ol-19-oic acid(EH-8),rutin(EH-9)5'-methoxy-8-methyl-6-prenyl-5,7-dihydroxy- 3',4'-methylenedioxy-flavone (EH-10). Compounds EH-3 to EH-10 was isolated for the first time from this plant and the structures were elucidated by spectroscopic analysis.
