中文摘要：

目的：研究圆锥石头花根中的化学成分。方法：用75%乙醇回流提取、乙酸乙酯和正丁醇依次萃取,采用硅胶、Sephadex LH-20、Rp-C18柱色谱法和制备液相色谱等方法分离纯化,根据光谱数据（一维、二维的核磁共振谱和质谱）及酸水解鉴定了化合物的结构并进行了-葡萄糖苷酶抑制活性测定。结果：从圆锥石头花根中分离得到2个新三萜多糖皂苷——圆锥石头花皂苷A（1）和B（2）,两者均具有较强的α-葡萄糖苷酶抑制活性。结论：化合物1和2是首次从该植物中分离得到的新化合物,其结构中的对甲氧基-桂皮酰基可能为决定相关活性的关键基团。

英文摘要：

AIM：To investigate chemical constituents of Gypsophila paniculata.METHODS：The compounds were isolated by silica gel,Sephadex LH-20,Rp-C18 column chromatography and preparative liquid chromatography.Their structures were elucidated by ESI-MS,NMR techniques （1H,13C,HMQC,HMBC,TOCSY） and acid hydrolysis.Moreover their α-glucosidase inhibition activity was evaluated compared with that of their aglycone.RESULTS：Two triterpenoid saponins,caryophyllacosides A （1） and B （2）,were isolated from the roots of Gypsophila paniculata,without having recourse to chemical degradation or modification.Both of them were found to have potent α-glucosidase inhibitiory activity.CONCLUSION：The two triterpenoid saponins are new boactive compounds.
