小无心菜中黄酮与酮类成分研究(英文)

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酮(5),1,5-二羟基酮-6-O-β-D-葡萄糖苷(6),5-羟基-1-甲氧基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。

Flavanoids and xanthones isolated from Arenaria serpyllifolia L.

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
