Abstract

From the whole plant of white clover, Trifolium repens, five new triterpenoid saponins, designated cloversaponins I-V, were isolated together with four known saponins, beta-D-glucoronopyranosylsoyasapogenol B, soyasaponin I, soyasaponin II and azukisaponin II as their methyl esters. Their structures were determined by 2H NMR and 13C NMR spectroscopy and chemical evidence.

摘要

从白车轴草（Trifolium repens）的全株中分离出五种新的三萜皂苷，命名为车轴草皂苷I - V，同时还分离出四种已知皂苷，即β - D - 葡糖醛酸吡喃糖基大豆皂醇B、大豆皂苷I、大豆皂苷II和赤豆皂苷II的甲酯。通过2H NMR和13C NMR光谱以及化学证据确定了它们的结构。
