Abstract

: A new flavanone glycoside, butin 4'-O-(2 ''-O-beta-D-apiofuranosyl)-beta-D-glucopyranoside (1), together with liquiritin (2), liquiritin apioside (3), isoliquiritri apioside (4), davidioside (5), quercetin (6), kaempferol (7), kaempferol 3-O-beta-D-glucopyranoside (8) and kaempferol 3-O-alpha-L-arabinofuranoside (9) were isolated from the marc of Rosa damascena flowers after industrial distillation of essential oil. This is the first report of the occurrence of compounds 2, 3, 4 and 5 in R. damascena. The structures of the isolated constituents were established on the basis of spectroscopic {UV, IR, ID, 2D NMR (DEPT, HMQC, HMBC and COSY)}, spectrometric (ESI-QTOF-MS), and chemical evidence.
