Abstract:
OBJECTIVETo investigate the chemical constituents from the leaves of Vaccinium bracteatum.
METHODMany column chromatographic techniques were used for the isolation and separation of chemical constituents. Their structures were elucidated on the basis of spectral analysis and chemical evidences.
RESULTTwelve compounds were isolated from the plant, and they were identified as chrysoeriol (1), scopoletin (2), trans-p-hydroxycinnamic acid (3), trans-p-hydroxycinnamic acid ethyl ester (4), cafeic acid ethyl ester (5), beta-sitosterol (6), iuteolin (7), quercetin (8), esculetin (9), cafeic acid (10), isolariciresinol-9-O-beta-D-xyloside (11), 10-O-trans-p-coumaroylsandoside (12).
CONCLUSIONCompounds 4, 5, 11, 12 were isolated from the genus Vaccinium for the first time, and compounds 1, 2, 9, 10 were isolated from this plant for the first time.
