摘  要:利用大孔吸附树脂柱色谱、硅胶柱色谱、ODS柱色谱及制备液相等方法,从盾叶薯蓣Dioscorea zingiberensis70%乙醇提取物中分离得到10个化合物,并通过核磁和质谱等波谱学方法分别鉴定它们的结构为胡芦巴皂苷XⅢa(1)、小花盾叶薯蓣皂苷(2)、胡芦巴皂苷IVa(3)、三角薯蓣皂苷(4)、protobioside(5)、lilioglycoside K(6)、盾叶新苷(7)、三角叶皂苷(8)、薯蓣次苷A(9)、延龄草皂苷(10)。其中,化合物1,3,5,6均为首次从该植物中分离得到。化合物1-10的体外血小板活性筛选表明,化合物7和8能够诱导血小板聚集,而化合物9具有显著抑制血小板聚集的作用。Using the absorbent resin, silica gel and ODS column chromatography as well as semi-preparative HPLC, ten compounds were isolated from 70% ethanol extract of tubers of Dioscorea zingiberensis C.H. Wright, and their structures were elucidated as trigoneoside XIIIa ( 1), parvifloside (2), trigoneoside IVa (3), dehoside (4), protobioside (5), lilioglycoside k (6), zingiberensis newsaponin I (7), dehonin (8), prosapogenin A of dioscin (9), and trillin (10) on the basis of NMR and MS spectral data analysis. Among these compounds, 1, 3, 5 and 6 were isolated from this plant for the first time. In the screening test on platelet aggregation, compounds 7 and 8 exhibited induction effect on platelet aggregation, while compound 9 exhibited significant inhibitory effect on platelet aggregation in vitro.
