Four new triterpenoid saponins were isolated from the roots of Gypsophila paniculata and G. arrostii. Their structures were elucidated using a combination of homo- and heteronuclear 2D NMR techniques, without having recourse to chemical degradation or modification. The saponins investigated are: 3-O-beta-D-galactopyranosyl-(1----2)-[beta-D-xylopyranosyl-(1----3)]-bet a-D- glucuronopyranosyl quillaic acid 28-O-beta-D-glucopyranosyl-(1----3)-[beta-D-xylopyranosyl-(1----4)]-alph a- L-rhamnopyranosyl-(1----2)-beta-D-fucopyranoside; 3-O-beta-D-galactopyranosyl-(1----2)-[beta-D-xylopyranosyl-(1----3)]-bet a- D-glucuronopyranosyl quillaic acid 28-O-beta-D-arabinopyranosyl-(1----4)-beta-D-arabinopyranosyl++ +-(1----3)-beta-D- xylopyranosyl-(1----4)-alpha-L-rhamnopyranosyl-(1----2)-beta-D-fucopyran oside; 3-O-beta-D-glucopyranosyl-(1----2)-beta-D-glucuronopyranosyl gypsogenin 28-O-beta-D-glucopyranosyl-(1----3)-[beta-D-xylopyranosyl-(1----4)]-alph a- L-rhamnopyranosyl-(1----2)-beta-D-fucopyranoside; 3-O-beta-D-xylopyranosyl-(1----3)-[beta-D-galactopyranosyl-(1----2)]-bet a- D-glucuronopyranosyl gypsogenin 28-O-beta-D-glucopyranosyl-(1----3)-[beta-D-xylopyranosyl-(1----4)-alpha -L- rhamnopyranosyl-(1----2)-beta-D-fucopyranoside.
从圆锥石头花和阿尔罗斯石头花的根部分离出了四种新的三萜皂苷。利用同核和异核二维核磁共振技术相结合的方法阐明了它们的结构，无需借助化学降解或修饰。所研究的皂苷有：3-O-β-D-吡喃半乳糖基-(1→2)-[β-D-吡喃木糖基-(1→3)]-β-D-吡喃葡糖醛酸基奎利亚酸28-O-β-D-吡喃葡萄糖基-(1→3)-[β-D-吡喃木糖基-(1→4)]-α-L-吡喃鼠李糖基-(1→2)-β-D-吡喃岩藻糖苷；3-O-β-D-吡喃半乳糖基-(1→2)-[β-D-吡喃木糖基-(1→3)]-β-D-吡喃葡糖醛酸基奎利亚酸28-O-β-D-吡喃阿拉伯糖基-(1→4)-β-D-吡喃阿拉伯糖基-(1→3)-β-D-吡喃木糖基-(1→4)-α-L-吡喃鼠李糖基-(1→2)-β-D-吡喃岩藻糖苷；3-O-β-D-吡喃葡萄糖基-(1→2)-β-D-吡喃葡糖醛酸基丝石竹皂苷元28-O-β-D-吡喃葡萄糖基-(1→3)-[β-D-吡喃木糖基-(1→4)]-α-L-吡喃鼠李糖基-(1→2)-β-D-吡喃岩藻糖苷；3-O-β-D-吡喃木糖基-(1→3)-[β-D-吡喃半乳糖基-(1→2)]-β-D-吡喃葡糖醛酸基丝石竹皂苷元28-O-β-D-吡喃葡萄糖基-(1→3)-[β-D-吡喃木糖基-(1→4)]-α-L-吡喃鼠李糖基-(1→)2-β-D-吡喃岩藻糖苷。
