摘要: 运用溶剂萃取结合硅胶、Sephadex LH-20、ODS及半制备液相等色谱方法从小无心菜 (Arenaria serpyllifolia L.) 的全草中分离得到8个已知化合物。应用光谱技术鉴定其结构分别为槲皮素(1), 槲皮素-7-O-α-L-鼠李糖苷(2), 槲皮素-3-O-α-L-鼠李糖苷(3), 3-O-甲基槲皮素(4), 1,5-二羟基口山酮(5), 1,5-二羟基口山酮-6-O-β-D-葡萄糖苷(6), 5-羟基-1-甲氧基口山酮(7) 和 6-deoxyisojacareubin (8)。以上化合物均为首次从小无心菜中分离得到, 化合物5-8为首次从蚤缀属植物中分离得到。

Abstract: Eight known compounds were isolated from the whole plants of Arenaria serpyllifolia L. by solvent fractionation and subsequent separations with silica gel, ODS, Sephadex LH-20 and semi-preparative HPLC chromatography. Their structures were determined by spectroscopic analysis and identified as quercetin (1), quercetin 7-O-α-L-rhamnoside (2), quercetin 3-O-α-L-rhamnoside (3), 3-O-methyl quercetin (4), 1,5-dihydroxyxanthone (5), 1,5-dihydroxyxanthone-6-O-β-D-glucoside (6), 5-hydroxy-1-methoxyxanthone (7) and 6-deoxyisojacareubin (8). All these compounds were isolated from this title plant for the first time, and compounds 5-8 were obtained from genus Arenaria for the first time
