Saponin and Sapogenol. XLI. Reinvestigation of the Structures of Soyasapogenols A, B, and E, Oleanene-Sapogenols from Soybean. Structures of Soyasaponins I, II, and III

A full account of the structure revision of soyasapogenols is presented.The structures of soyasapogenols A, B, and E have been confirmed to be expressed as 3β,21β,22β,24-tetrahydroxyolean-12-ene (1), 3β,22β,24-trihydroxyolean-12-ene (2), and 3β,24-dihydroxyolean-12-en-22-one (5), respectively, rather than the previously reported 3β,21α,22α,24-tetrahydroxyolean-12-ene (1'), 3β,21α,24-trihydroxyolean-12-ene (2'), and 3β,24-dihydroxyolean-12-en-21-one (5').In consequence, the structures of soyasaponins I, II, and III are formulated as 3-O-2)-β-D-galactopyranosyl(1->2)-β-D-glucuronopyranosyl>soyasapogenol B (8), 3-O-2)-α-L-arabinopyranosyl(1->2)-β-D-glucuronopyranosyl>soyasapogenol B (9), and 3-O-2)-β-D-glucuronopyranosyl>soyasapogenol B (10), respectively.Keywords - soybean; Glycine max; oleanene-sapogenol; soyasapogenol A; soyasapogenol B; soyasapogenol E; soyasaponin I; soyasaponin II; soyasaponin III; bioactive triterpene oligoglycoside
