Abstract:Four hydroquinone diglycoside acyl esters, glypentosides A-C (1-3) and seguinoside F (4), were isolated from the stems of Glycosmis pentaphylla. Glypentosides A-B (1-2) were identified as compounds and designated as methoxyquinol 4-O-[(5-O-trans-p-coumaroyl)-beta-d-apiofuranosyl-(1-->2)-beta-d-glucopyranoside] (1) and 4-demethylantiarol 4-O-[(3-methoxy-4-hydroxy-benzoyl)-beta-d-apiofuranosyl-(1-->2)-beta-d-glucopyranoside] (2). Glypentoside C (3) is a hydroquinone diglycoside acyl ester with a neolignan moiety in the acyl unit. Their structures were elucidated by the combination of one- and two-dimensional NMR analysis, mass spectrometry and chemical evidences.
Keywords:Glycosmis pentaphylla   Rutaceae   Glypentosides A-C   Hydroquinone glycosides   Acyl esters   Apiosyl-(1 → 2)-glucosides
