WU Zhi-Jun,OUYANG Ming-An,YANG Chong-Ren # (Kunming Institute of Botany, The Chinese Academy of Sciences, Kunming 650204)  
Four new oleanane triterpenoidal saponins, arillatanoside A~D, together with a known saponin polygalasaponin XXXV were isolated from the stem bark of Polygala arillata. The structures of new saponins were established to be 28-O-α-L-arabinopyranosyl-(1→3)-β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-β-D-fucopyranosyl presenegenin-3-O-β-D-glucopyranoside, 28-O-β-D-galactopyranosyl-(1→4)-[α-L-arabinopyranosyl-(1→3)]-β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl -(1→2)-[4-O-acetyl]-β-D-fucopyranosyl presenegenin-3-O-β-D-glucopyranoside, 28-O-β-D-galactopyranosyl-(1→4)-[α-L-arabinopyranosyl-(1→3)]-β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-β-D-fucopyranosyl presenegenin 3-O-β-D-glucopyranoside and 28-O-β-D-galactopyranosyl-(1→4)-[α-L-arabinopyranosyl-(1→3)]-β-D-xylopyranosyl-(1→4)-[β-D-apiofurarnosyl-(1→3)]-α-L-rhamnopyranosyl-(1→2)-β-D-fucopyranosyl presenegenin-3-O-β-D-glucopyranoside, respectely, by FAB-MS and NMR spectroscopy.
