ABSTRACT
The chemical constituents of Vaccinium bracteatum were studied by means of macroporous resin, ODS column chromatography and preparative HPLC. Eleven compounds were isolated from this plant. By using ESI-MS and NMR, the structures of the eleven compounds were determined as 10-O-trans-p-coumaroyl-6alpha-hydroxyl-dihydromonotropein (1), 10-O-cis-p-coumaroyl -6alpha-hydroxyl-dihydromonotropein (2), vaccinoside (3), 10-O-cis-p-coumaroyl monotropein (4), isolariciresinol-9-O-beta-D-xyloside (5), tectoridin (6), vicenin-3 (7), quercetin-3-O-alpha-L-rhamnoside (8), quercetin-3-O-alpha-L-arabinopyranoside (9), quercetin-3-O-beta-D-galactopyranoside (10), and quercetin-3-O-beta-D-glucuronide (11), respectively. Compounds 1 and 2 are new, and compounds 4, 6 and 7 are isolated from the genus Vaccinium for the first time.
