作者在研究糖甙时,从唐松草中获得二个新的环阿尔廷型糖甙,命名为唐松草甙Ⅻ(thalictoside)和唐松草甙ⅩⅢ。并对其结构进行了探讨。 唐松草约4.9kg,甲醇提取,将提取物用苯和水(1:1,v/v)进行分离。水溶部分用DiaionHP-20柱层析,流动相为甲醇-水(0％→30％→50％→70％→90％→100％),得到7个组分(1～7)。组分7(22.1g)通过葡聚糖凝 When studying sugar glycosides, the authors obtained two new ring-shaped Altin-type sugar glycosides from Thalictrum, named Thalitoside XII (thalictoside) and Tangsongcao XIII. And its structure was discussed. About 4.9 kg of Don pine grass is extracted with methanol, and the extract is separated with benzene and water (1:1, v/v). The water-soluble fraction was chromatographed on a Diaion HP-20 column. The mobile phase was methanol-water (0%→30%→50%→70%→90%→100%) to give 7 components (1 to 7). Component 7 (22.1 g) condenses through dextran
