Arbutin derivatives from the buds of Vaccinium dunalianum and their MS/MS spectrometric fragmentations

摘要

Four arbutin derivatives were isolated from the buds of Vaccinium dunalianum in which 4-hydroxyphenyl-6'-(3 ''-O-beta-D-glucopyranosyl-4 ''-hydroxycinnamoyl)-O-beta-D-glucopyranoside (1) was a new compound. The structure of the new compound was determined on the basis of NMR and HR-ESI-MS data. All the arbutin derivatives were subjected to the MS/MS analyses from which the MS/MS spectrometric fragmentations were summarized.
