OLIGOSACCHARIDE POLYESTERS FROM ROOTS OF POLYGALA-GLOMERATA

Seven new sucrose and oligosaccharide esters, glomeratoses A-G, togeth er with four known compounds, 4,5-trimethoxycinnamoyl]-beta-D-fructofu ranoysl-(2 --> 1)-(6-O-benzoyl)-alpha--D-glucopyranoside, 3-O-(E)-sina poyl-beta-D-fructofuranosyl-(2 --> 1)-[6-O-(E)-sinapoyl]-alpha-D-gluco pyranoside, tenuifoliside C and reiniose G were isolated from the root s of Polygala glomerata. Glomeratoses A-G were elucidated as 4,5-trime thoxycinnamoyl]-beta-D-fructofuranosyl-(2 --> 1)-alpha-D-glucopyranosi de, 3-O-(E)-sinapoyl-beta-D-fructofuranosyl-(2 --> 1)-[6-O-(E)-p-couma royl]-alpha-D-glucopyranoside, 4,5-trimethoxycinnamoyl]-beta-D-fructof uranosyl-(2 --> 1)-[6-O-(E)-p-coumaroyl]-alpha-D-glucopyranoside, 4,5- trimethoxycinnamoyl]-beta-D-fructofuranosyl-(2 --> ,4,5-trimethoxycinn amoyl]-alpha-D-glucopyranoside, )-beta-D-fructofuranosyl]}-alpha-D-glu copyranoside intramolecular ester, -coumaroyl-(3-O-benzoyl)-beta-D-fru ctofuranosyl-(2 --> 1)-[beta-D-glucopyranosyl-(1 --> 2)]-[6-O-acetyl-b eta-D-glucopyranoysl-(1--> E)-feruloyl]-(6-D-acetyl)-alpha-D-glucopyra noside, umaroyl-(3-O-benzoyl)-beta-D-fructofuranosyl-(2--> 1)-[beta-D- glucopyranosyl-(1 --> 2)]-[6-O-acetyl-beta-D-glucopyranoside-(1--> yl] }-[6-O-(E)-p-coumaroyl]-alpha-D-glucopyranoysl, respectively, on the b asis of chemical and Spectral evidence.
