Abstract:

Eight terpenoids have been isolated from the ethyl acetate extract of Ixeridium chinense (Thunb.) Tzvel by using column chromatography and preparative thin layer chromatography. Structures for all these compounds were proposed on the basis of spectroscopic data, together with comparing their spectral data with those of the corresponding compounds reported in the literature. They were identified as β-amyrin (1), 3β-hydroxyl-20(30)-taraxastene (2), olean-12-ene-3β-ol (3), lupol (4), 10-hydroxyeremophil-7(11)-en-12,8α-olide (5), ursan-12,20(30)-dien-3β,28-diol (6), 3β,8α-dihydroxyl-6β-angloxyeremophil-7(11)-en-12,8β-olide (7) and ursolic acid (8). Compounds 1-8 were obtained from this plant for the first time.
