Abstract:Objective:To investigate the chemical constituents form stems of Kadsura interior.Methods:The compounds were isolated by various chromatographic techniques including silica gel column chromatography,Sephadex LH-20,ODS reverse phase column chromatography and reversed-phase HPLC.The structures were elucidated by physiochemical property and spectral analysis.Results:Fifteen compounds were isolated and identified as licarin A(1),kadsurin(2),heteroclitin D(3),heteroclitin G(4),8a-hydroxypinoresinol(5),interiorin C(6),heteroclitin E(7),prinsepiol(8),schiarisanrin C(9),benzoyl oxokadsuranol(10),pinoresinol(11),coumarinlignan(12),piperitol(13),heteroclitin I(14)and dihydrodehydrodiconiferyl alcohol(15),Conclusion:Compounds 1,5,7,8,10-15 were isolated from K.interior for the first time.
