野百合(Crotalaria sessiliflora L.)全草经75%乙醇渗滤提取,采用柱色谱技术对提取物分离纯化,通过波谱数据鉴定了得到的12个化合物,分别为:野百合素B(1)、槲皮素(2)、山柰酚(3)、soyasapogenol B(4)、羊齿烯醇(5)、新海胆灵A(6)、对羟基苯甲酸乙酯(7)、咖啡酸乙酯(8)、5,7-二羟基色原酮(9)、响铃豆素A(10)、butesuperin B(11)和橙黄胡椒酰胺乙酸酯(12)。化合物1为新化合物,化合物3~12均是首次从该植物中分离得到。 The extracts of Crotalaria sessiliflora L.were isolated by diafiltration with 75% ethanol. The extracts were isolated and purified by column chromatography. Twelve compounds were identified by spectroscopic data, including wild lutein B (1), (2), kaempferol (3), soyasapogenol B (4), sheep allenol (5), new sea urchin A (6), ethyl p-hydroxybenzoate (7), ethyl caffeate (8), 5,7-dihydroxychromophorone (9), bellylin A (10), butesuperin B (11), and angostamine acetate (12). Compound 1 is a new compound, and compounds 3 ~ 12 are isolated from this plant for the first time.
