Crude blueberry extract was separated by repeated silica column fractionation and a N-SMase assay was used to determine fractions that inhibited enzyme activity. (a) Representative thin layer chromatography of the initial fractionation using dichloromethane/methanol as the solvent (92/8) with fraction #1 selected for further separation. (b) Representative thin layer chromatography of the second fractionation using dichloromethane/methanol as the solvent (85/15) with fraction #28 selected for further separation. (c) Following a clean-up fractionation, quercetin-3-O-arabinoside was identified by LC-MS (ESI, Q-TOF, in positive ion mode) and 1H-NMR (inset) as the primary component of fraction 1,28.
