摘要:

目的 对延胡索的生物碱类成分及其醌还原酶(QR)诱导活性进行系统研究。方法 运用色谱学和波谱学方法分离鉴定了9个化合物的结构，并对分离得到的化合物单体进行QR诱导活性测定。结果 从该植物中分得9个化合物，分别鉴定为d-紫堇碱(Ⅰ)、去氢海罂粟碱(Ⅱ)、四氢巴马汀(Ⅲ)、原阿片碱(Ⅳ)、α-别隐品碱(Ⅴ)、四氢非洲防己碱(Ⅵ)、去氢紫堇碱(Ⅶ)、小檗碱(Ⅷ)、巴马汀(Ⅸ)。QR诱导活性筛选结果表明d-紫堇碱(Ⅰ)和四氢非洲防己碱(Ⅵ)显示了一定的QR诱导活性。结论 首次对延胡索中的生物碱单体进行了QR诱导活性测定，考察结果具有实际指导意义。

Abstract:

OBJECTIVE To study the chemical constituents from Corydalis Rhizoma and their quinone reductase(QR) inducing activties in vitro. METHODS Chromatographic and spectroscopic methods were used to isolate and identify the alkaloids from the ethanol extraction of Corydalis Rhizoma. QR induction assay was employed to investigate the QR inducing activities of the isolated alkaloids. RESULTS Nine compounds were isolated and identified as d-corydaline(Ⅰ), dehydroglaucine(Ⅱ), tetrahydropalmatin(Ⅲ), protopine(Ⅳ), α-allocryptopine(Ⅴ), tetrahydrocolumbamine(Ⅵ), dehydrocorydaline(Ⅶ), berberine(Ⅷ), palmatine(Ⅸ). Among these alkaloids, d-corydaline(Ⅰ) and tetrahydrocolumbamine(Ⅵ) possessed moderate QR inducing activities in vitro. CONCLUSION The QR inducing activities of alkaloids from Corydalis Rhizoma were investigated for the first time, and the results generally show a positive significance.
