STUDIES ON CONSTITUENTS OF SABIA SWINHOEI HEMSL. EX FORB. ET HEMSL.

Eight compounds were isolated from the cerial part of sabia swinhoei Hemal.exFotb.et Hemsl.Their structures were idemtified sabialactone(Ⅰ),sabianone(Ⅱ),bisabolene(Ⅲ),1-triacontanol(Ⅳ),β-sitosterol(Ⅴ),octacosanoic acid(Ⅵ),oleanolic acid (Ⅶ) and daucosterol(Ⅷ)by phyaicochemical constants and spectral analyses.Ⅰand Ⅱ are new compounds,their structures were elucidated as 13α-hydroxy-3-oxo-oleanan-28- 12β-lactone(Ⅰ)and 28-hydroxy-olean-13(18)-en- 3- one(Ⅱ).
