Studies on chemical constituents of Belamcanda chinensis.

Objective To investigate the chemical constituents of 80% ETOH extract from rhizome of Belamcanda chinensis(L.)DC.Methods The constituents were isolated and purified by chromatography on silica gel,Sephadex LH-20 and HPLC;the structures of the compounds were determined by MS and NMR spectral analysis.Results Ten constituents were identified from rhizome of Belamcanda chinensis(L.)DC,including tectoridin(Ⅰ),acetovanillone(Ⅱ),4-hydroxy-acetophenone(Ⅲ),β-sitosterol(Ⅳ),β-daucosterol(Ⅴ),5,7,4′-trihydroxyl-3′,5′-dimethoxyflavone(Ⅵ),luteolin (Ⅶ),apigenin(Ⅷ),5,7,4′-trihydroxyflavanones(Ⅸ),and isorhamnetin(Ⅹ).Conclusion CompoundsⅥ,Ⅶ,Ⅷ,andⅨ have been isolated from rhizome of Belamcanda chinensis for the first time.
