Studies on chemical constituents of Belamcanda chinensis / 第二军医大学学报

ABSTRACT

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: Compounds VI, VI, VIII, and IX have been isolated from rhizome of Belamcanda chinensis for the first time.
