Abstract

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.

Description

technical field [0001] The invention relates to a resveratrol tetramer compound (Vaticaffinol) and its preparation method, as well as the application of the resveratrol tetramer compound (Vaticaffinol) in the prevention and treatment of hyperuricemia and gout, belonging to medical technology field. Background technique [0002] Resveratrol (resveratrol, referred to as Res) is a non-flavonoid polyphenol compound, and Japanese Tokaoka first obtained it from veratrol (Res veratrol) in 1940. Veratrum grangiflorum ) is separated from the root. In 1963, Nonomura et al proposed that resveratrol is an active ingredient of certain herbal medicines for treating inflammation, lipid metabolism disorders and cardiovascular diseases. With the in-depth research on resveratrol, it has been shown that resveratrol has anti-cancer, anti-oxidation, anti-bacterial, anti-inflammatory and other effects, and can be widely used in medicine, health products, food, cosmetics and other fields.
