  Studies on the constituents of leguminous plants. Part XXXI. Four New Oleanene Glycosides from Sophorae Subprostratae Radix. III.

  摘要：

  In a previous paper, we reported the isolation and structure determination of three new oleanene glycosides, subprosides I, II and III, together with four known glycosides, kudzusaponin A3, abrisaponin I, soyasaponin II and dehydrosoyasaponin I from Sophora subprostrata CHUX et T. CHEN (Leguminosae). In a continuing study on this crude drug, we report the characterization of four more new minor glycosides, subprosides IV (1), V (2), VI (3) and VII (4). Their chemical structures could be represented as 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-galactopyranosyl-(1→2)-β-D-glucuronopyranosyl abrisapogenol D 30-O-β-D-glucopyranoside (1), 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-galactopyranosyl-(1→2)-β-D-glucuronopyranosyl wistariasapo-genol B 30-O-β-D-glucopyranoside (2), 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-galactopyranosyl-(1→2)-β-D-glucuronopyranosyl kudzusapogenol A 21-O-α-L-rhamno-pyranoside (3) and 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-galactopyranosyl-(1→2)-β-D-glucuronopyranosyl soyasapogenol B 22-O-β-D-glucopyranosyl-(1→2)-β-D-xylopyranoside (4) on the basis of chemical and physiochemical evidence.
