VOMIFOLIOL 9-O-β-D-GLUCOPYRANOSYL-4-O-β-D-XYLOPYRANOSYL-6-O-β-D-GLUCOPYRANOSIDE: A TRISACCHARIDE GLYCOSIDE FROM APPLE FRUIT

Article abstract of DOI:10.1016/0031-9422(92)80035-D

From a methanolic extract of neutralized apple fruit pulp, a minor compound was isolated by adsorption chromatography on both XAD and PVPP resins followed by rotation locular countercurrent chromatography (RLCC).Clean-up for subsequent spectroscopic studies was performed by preparative HPLC on RP-18 and RP-select B phases.Data available from UV, NMR and mass spectroscopy together with the results obtained by enzymatic and acid hydrolyses revealed the structure of the polar glycoside as vomifoliol 9-O-β-D-glucopyranosyl-4-O-β-D-xylopyranosyl-6-O-β-D-glucopyranoside.Key Word INdex - Malus sylvestris; Rosaceae; apple fruit; vomifoliol trisaccharide glycoside; vomofoliol 9-O-β-D-glucopyranosyl-4-O-β-D-xylopyranosyl-6-O-β-D-glucopyranoside.
