Abstract:

Aim To studythe chemical constituents of Euphorbia ebracteolata Hayata. Methods Column chromatography was used in the isolation procedure, while the structures of isolated compounds were elucidated by spectral data. Results Six compounds were isolated and their structures were identified as baccatin (1), 3-acetyl-β-amyrin (2), 3,3'-diacetyl-4,4'-dimethoxy- 2,2',6,6'-tetrah ydroxy diphenylmethane (3), 2,4- dihydroxy-6- methoxy-3-methyl acetophenone (4), β- sitosterol(5), and daucosterol (6). Conclusion Baccatin was obtained from Euphorbia ebracteolata for the first time.

Key words: Euphorbia ebracteolata Hayata, Euphorbia ebracteolata Hayata, chemical constituents, chemical constituents, baccatin, baccatin
