目的对软蒺藜的化学成分进行研究。方法采用硅胶柱色谱、聚酰胺柱色谱及Sephadex LH-20柱色谱等方法进行分离纯化,通过理化方法以及波谱分析鉴定化合物的结构。结果从软蒺藜体积分数为75%的乙醇提取物中分离了5个化合物,分别鉴定为苜蓿素(1)、异鼠李素-7-O-α-L-吡喃鼠李糖苷(2)、异鼠李素-3-O-β-D-吡喃葡萄糖-7-O-α-L-吡喃鼠李糖苷(3)、β-谷甾醇(4)、胡萝卜苷(5)。结论化合物2、3为首次从滨藜属植物中分离得到。
Objective To study the chemical composition of soft palate. Methods The compounds were isolated and purified by silica gel column chromatography, polyamide column chromatography and Sephadex LH-20 column chromatography. The structures of the compounds were identified by physicochemical methods and spectral analysis. Results Five compounds were isolated from ethanol extracts with a volume fraction of 75% soft palate and identified as alizarin (1) and isorhamnetin-7-O-α-L-rhamnopyrantoside (2). Isorhamnetin-3-O-β-D-glucopyranose-7-O-α-L-rhamnopyranoside (3), β-sitosterol (4), and carotenoid (5). Conclusion Compounds 2 and 3 were isolated from Atriplex for the first time.
