AbstractSix new apiosyl-( 1 -> 6)-glucosyl isoflavones ( 1-6) and four known ones were isolated from the stems of Glycosmis pentaphylla. The structures of the new glycosides are 3', 7-dihydroxy-4', 5,6-trimethoxyisoflavone 7-O-( 5-O-trans-p-coumaroyl),- beta-D-apiofuranosyl-( 1 -> 6)-beta-D-glucopyranoside ( 1), 2', 7-dihydroxy- 4', 5', 5,6-tetramethoxyisoflavone 7-O-( 5-O-trans-p-coumaroyl)-beta-D-apiofuranosyl-( 1 -> 6)-beta-D-glucopyranoside ( 2), 2', 7-dihydroxy- 4', 5', 5,6-tetramethoxyisoflavone 7-O-beta-D-apiofuranosyl-( 1 -> 6)-beta-D-glucopyranoside ( 3), 7-hydroxy-4', 8-dimethoxyisoflavone 7-O-beta-D-apiofuranosyl-( 1 -> 6)-beta-D-glucopyranoside ( 4), 7-hydroxy-4', 6-dimethoxyisoflavone 7-O-beta-D-apiofuranosyl-( 1 -> 6)-beta-D-glucopyranoside ( 5), and 4', 5-dihydroxy-3', 7-dimethoxyisoflavone 4'-O-beta-D-apiofuranosyl-( 1 -> 6)-beta-D-glucopyranoside ( 6). Their structures were established primarily by NMR experiments and chemical methods.
