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-beta-D-glucopyranosyl-4-O-beta-D-xylopyranosyl-6-O-beta-D-glucopyran oside.

D002845	Chromatography	Techniques used to separate mixtures of substances based on differences in the relative affinities of the substances for mobile and stationary phases. A mobile phase (fluid or gas) passes through a column containing a stationary phase of porous solid or liquid coated on a solid support. Usage is both analytical for small amounts and preparative for bulk amounts.	Chromatographies

D006027	Glycosides	Any compound that contains a constituent sugar, in which the hydroxyl group attached to the first carbon is substituted by an alcoholic, phenolic, or other group. They are named specifically for the sugar contained, such as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc. Upon hydrolysis, a sugar and nonsugar component (aglycone) are formed.
