Chemical Constituents from Coptis Chinensis Franch

Objective:Aim To study the chemical constituents of Co.chinensis Franch.Method: The compounds were separated and purified by column chromatography and their structures were established by spectroscopic methods.Result: Seven compounds were isolated from the chloroform extract of C.chinensis Franch,whose structures were determined as(1),vanillic acid(1),lariciresinol(2),protocatechuic acid ethyl ester(3),berberine(4),3,4,α-trihydroxy-methyl phenylpropionate(5),N-tran-feruloyltyramine(6),Oxyberberine(7).Conclusion: Compounds 3,5,6were isolated from this genus for the first time.
