Objective: In order to study the chemical constituents of Cryptolepis sinensis. Method:Column chromatography on Silica gel,RP-l8 and Sephadex LH-20 were applied for the isolation and purification of the constituents. The structures were elucidated on the basis of spectral analysis,chemical evidences and by comparison with the data reported in literatures. Result: From the crude CHCl3 fraction of the Et OH extract of C.sinensis,11 phenylpropanoids were isolated and identified as( +)-pinoresinol( 1),( +)-8-hydroxy-pinoresinol( 2),( +)-syringaresinol( 3),horsfieldin( 4),balanophonin( 5),ficusesquilignan A( 6),ficusesquilignan B( 7),isoscopoletin( 8),7-hydroxy-6,8-dimethoxycoumarin( 9) patuletin( 10) and methyl sinapate( 11).Conclusion: All compounds 1-11 were isolated and identified from C. sinensis for the first time.
