In addition to the known soyasaponin I, 3-O-[α-L-rhamnopyranosyl(1→2)-β-D-galactopyranosyl(1→2-β-D-glucuronopyranosyl]-22-O-[β-D-glucuronopyranosyl(1→2)-β-D-glucopyranosyl]soyasapogenol B, soyasaponin II, 3-O-β-D-glucopyranosyl sitosterol, 3-O-β-D-glucopyranosyl stigmasterol and 3-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyranosyl]oct-1-ene-3-ol, the new saponin, 3-O-α-L-rhamnopyranosyl(1→2)-β-D-galactopyranosyl(1→2)-β-D-glucuronopyranosyl]-22-O-β-D-glucopyranosyl soyasapogenol B (2) was isolated and characterised from the seed saponins fraction of Trifolium resupinatum. The structural determination is based on spectroscopic methods (including DQF-COSY, HETCOR, TOCSY, ROESY and NOEs experiments).
