摘要
采用硅胶、反相硅胶和凝胶柱色谱进行分离、纯化,研究茜草科植物猪殃殃全草甲醇洗脱部位的化学成分。化合物经质谱和核磁等波谱分析方法确定结构得到8个化合物,分别为6-O-乙酰鸡屎藤次苷(1),6α-羟基京尼平苷(2),京尼平苷酸(3),6β-羟基京尼平苷(4),交让木苷(5),6α-甲氧基京尼平苷酸(6),去乙酰基车叶草苷酸(7),光泽汀-3-O-葡萄糖苷(8)。化合物1—6为首次从拉拉藤中分离得到,其中化合物4,6是从该属中首次分到。
To study the chemical constituents in methanol fraction of Galium aparine L. ,the 75% alcohol extract of G. aparine were subjected to silica gel, ODS and Sephadex LH-20 column chromatography. The isolates were identified with the physicochemical properties and spectra data. Eight compounds from G. aparine, were identified as 6-O-acetylscandoside (1) ,6α-hydroxy geniposide (2), geniposidic acid (3), 6β-hydroxy geniposide (4), daphylloside (5) ,6α-methoxy geniposidic acid(f) ,deacetylasperulosidic acid(7) ,lucidin-3-O-glucoside(8). Compounds 1-6 were isolated from G. aparine for the first time, and compounds 4 and 6 were firstly isolated from the genus Galium.
