Abstract:
AIMTo study the bioactive constituents of the flower of Castanea mollissima Blume.
METHODSCompounds were isolated and purified by column chromatography of silica gel and TLC. Structures were determined by various spectroscopic data, including IR, 1HNMR and 13CNMR, EIMS, FABMS and HMBC as well as comparison of the data with those reported in literatures.
RESULTSFive compounds were isolated and elucidated as myricetin (I), quercetin (II), gallic acid (III), 4-quinolinone-2-caboxylic acid (IV), (+) -isolariciresinol-9'-O-alpha-L-rhamnoside (V).
CONCLUSIONThese compounds were separated from the flower for the first time and compound V is a new compounds, named chestnutlignansoide.
