Abstract:
Eight compounds were isolated from the whole plants of Crossostephium chinense. Their structures were identified on the basis of analysis of spectral data. Eight compounds were taraxeryl acetate (1), taraxerol (2), alpha-amyrin acetate (3), beta-amyrin acetate (4), beta-sitosterol (5), 3beta-acetoxy-12-ursen-11-one (6), uracil (7) and 5-O-methyl-myo-inositol (8). Compounds 3-8 were isolated from the plant for the first time.
