Abstract
Polyscias guilfoylei Bail has just studied by our group. From leaves of this plant, four compounds had been isolated: isophytol, oleanolic acid, 3-0-B-D glucopyranosylspinasterol and 3-0-B-D-glucopyranosyloleanolic acid [5]. Now we presented five saponins isolated from leaves of this plant: B-D-glucuronopyranosyloleanolic acid (1), a mixture of two saponins of 3-0-B-D-glucopyranosyl-(1→3)-B-D-glucuronopyranosyloleanolic acid (2a) and 3-0-B-D-glucopyranosyl-(1→4)-B-D-glucurono-pyranosyloleanolic acid (2b) with the ratio of (2:3), 3-0-B-D-glucopyranosyl-(1→3)-[B-D-gluco-pyranosyl-(1→4)3-B-D glucuronopyranosyloleanolic acid (3), 3-0-B-D-glucopyranosyl-(1→2)-(B-D-glucopyranosyl (1→4 )]-B-D-glucuronopyranosyloleanolic acid (4) and 3-0-B-D-glucopyranosyl-( 1→4)-B-D- glucuronopyranosyloleanolic acid 28-0-B-D-glucopyranosyl ester (5). Their chemical structures were established by spectroscopic analysis.
