Isoflavone Diglycosides from Glycosmis pentaphylla

Six 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)-β-d-apiofuranosyl-(1→6)-β-d-glucopyranoside (1), 2‘,7-dihydroxy-4‘,5‘,5,6-tetramethoxyisoflavone 7-O-(5-O-trans-p-coumaroyl)-β-d-apiofuranosyl-(1→6)-β-d-glucopyranoside (2),...
