Study on the chemical constituents of Kadsura heteroclita

The chemical constituents of Kadsura heteroclite(Roxb.) Craib were studied and eight compounds were isolated by silica column chromatography and recrystallization.The structures of the compounds were elucidated as kadsudila-ctone(1),changnanic acid(2),nigranoic acid(3),acetyl aleuritolic acid(4),(+)-dihydrodehydrodiconiferyl alcohol-9-O-D-glu-copyranoside(5),isolariciresinol-9-O-β-D-xylopyranoside(6),β-sitosterol(7) and daucosterol(8) by spectral analysis.Compounds 1,5 and 6 were isolated from this plant for the first time.
