Saponins from Trifolium repens.
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.
