摘要
研究中药射干[Belamcanda chinensis(L.)DC]的化合物成分。用70%乙醇提取,减压浓缩至浸膏,水溶解后得滤液和沉淀,滤液由大孔吸附树脂AB-8纯化,沉淀由乙酸乙酯溶解,用聚酰胺薄层层析、Sephadex LH-20等方法进一步提纯各组分,利用核磁共振鉴定结构。结果表明:该射干经分离得到5个化合物,分别为野鸢尾黄素(irisflorentin)、鸢尾苷元(tectorigenin)、鸢尾苷(tectoridin)、草夹竹桃甙(androsin)、鸢尾甲苷A(iristectorin A),其中草夹竹桃甙为毒性成分,首次在射干中发现。
Some componential analysis of isoflavonoids of Belamcanda Chinensist（L.）DC was carried out.Extract isoflavonoids with 70% ethyl alcohol,concentrate the mixture with decompressor to extractum,get filtrate and precipitate after dissolving with distilled water.Purify filtrate with macroporous resin AB-8,dissolve precipitate with ethyl acetate,continue to purify these components with polyamide thin-layer chromatography and Sephadex LH-20,determinate these structure with nuclear magnetic resonance.The results showed that the purified Belamcanda chinensis（L.）DC had five compounds： irisflorentin,tectorigenin,tectoridin,androsin and iristectorin A.Androsin is discovered firstly in Belamcanda Chinensist（L.）DC,and it is the toxicity component.
