| Abstract: | Objective To study the chemical constituents of Ramulus Cinnamomi.Methods Compounds were isolated by various kinds of column chromatography on silica gel,Sephadex LH-20 and Pe-HPLC,and their structures were identified by the physico-chemical characters and spectral analysis.Results Eleven known compounds were isolated and their structures were identified as trans-cinnamic acid(1),taxifolin(2),protocatechuic acid(3),trans-o-hydroxy cinnamic acid(4),protocatechuic aldehyde(5),benzoic acid(6),trans-o-methoxy cinnamic acid(7),cis-o-methoxy cinnamic acid(8),4-hydroxybenzoic acid(9),coumarin(10),daucosterol(11).Conclusion Compound 5 was isolated from the Cinnamomum genus for the first time,and compounds 2,4,6,8,9 were isolated from Cinnamomum cassia Presl.for the first time. |
