Abstract
Objective: To study the chemical constituents from active extraction of immunity composite decoction.Methods: The constituents were separated and purified by column chromatography on silica gel and sephadex LH20.Their structures were elucidated on the basis of spectra data.Results: Sixteen compounds were isolated and identified as cryptotanshinone,dihydrotanshinone Ⅰ,tanshinone Ⅰ,tanshinone ⅡA,oxybenzoic acid,ferulic acid,P-hydroxybenzcic acid,caffeic acid,protocatechuic acid,scopoletin,galic acid,caffeotannic acid,P-coumaric acid,protocatechualdehyde,benzoic acid,brenzcatechin.Conclusion: All of compounds were isolated from immunity composite decotion for the first time.
