The invention relates to a
resveratrol tetramer compound and its preparation method. The preparation method comprises: (1) subjecting the twigs of dipterocarpus alatus to
alcohol extraction for preparing extract, (2) conducting sample loading by a dry method, (3) carrying out
elution with mobile phase eluent, and (4) performing gel
column chromatography. The invention also relates to application of the
resveratrol tetramer compound in medicaments for preventing or treating
hyperuricemia and
gout or in
health food. The extraction and purification process of the
resveratrol tetramer compound provided in the invention
dose not employ a reversed phase and a semi-preparative column, so that the technology has simple process and high yield. In addition, compared with inventions directed at
gout and
hyperuricemia, the resveratrol tetramer compound of the invention is a monomeric compound, which, as a natural
uric acid lowering agent, has clear effective components and an obvious
uric acid lowering effect. Being able to serve as a
quality standard, the compound of the invention is convenient and reliable, thus providing a scientific basis for its clinical application.
