Oligosaccharide polyesters from roots of Polygala glomerata.
Seven new sucrose and oligosaccharide esters, glomeratoses A-G, together with four known compounds, 3-O-[(E)-3,4,5-trimethoxycinnamoyl]-beta-D-fructofuranosyl-(2-->1) - (6-O-benzoyl)-alpha-D-glucopyranoside, 3-O-(E)-sinapoyl-beta-D-fructofuranosyl-(2-->1)-[6-O-(E)-sinapo yl]-alpha-D- glucopyranoside, tenuifoliside C and reiniose G were isolated from the roots of Polygala glomerata. Glomeratoses A-G were elucidated as 3-O-[(E)-3,4,5-trimethoxycinnamoyl]-beta-D-fructofuranosyl-(2-->1) -alpha-D- glucopyranoside, 3-O-(E)-sinapoyl-beta-D-fructofuranosyl-(2-->1)-[6-O-(E)-p- coumaroyl]-alpha-D-glucopyranoside, 3-O-[(E)-3,4,5-trimethoxycinnamoyl]-beta-D-fructofuranosyl-(2-->1) -[6-O-(E)- p-coumaroyl]-alpha-D-glucopyranoside, 3-O-[(E)-3,4,5-trimethoxycinnamoyl]-beta-D-fructofuranosyl-(2-->1) -[6-O-(E)- 3,4,5-trimethoxycinnamoyl]-alpha-D-glucopyranoside, 1-O-{6-O-[3-O-(E,E)-(beta, beta'-bis-sinapoyl)-beta-D-fructofuranosyl]}-alpha- D-glucopyranoside intramolecular ester, 1-O-(E)-p-coumaroyl-(3-O-benzoyl)-beta-D- fructofuranosyl-(2-->1)-[beta-D-glucopyranosyl-(1-->2)]-[6-O-acetyl-beta -D- glucopyranoysl-(1-->3)]-[4-O-(E)-feruloyl]-(6-D-acetyl)-alph a-D- glucopyranoside, 1-O-(E)-p-coumaroyl-(3-O-benzoyl)-beta-D-fructofuranosyl-(2-->1)-[ beta-D- glucopyranosyl-(1-->2)]-[6-O-acetyl-beta-D-glucopyranoside-(1-->3)]-{4-O - [4-O-beta-D-glucopyranosyl-(E)-feruloyl]}-[6-O-(E)-p-coumaroyl+ ++]-alpha- D-glucopyranosyl, respectively, on the basis of chemical and spectral evidence.
