Problems solved by technology

[0004] The curative effect of traditional Chinese medicine in treating hyperuricemia and gout is remarkable, but there are some deficiencies in the use of traditional Chinese medicine in several aspects: 1. Conventional preparation and taking methods are inconvenient, such as decoction, time-consuming, heavy taste when taking, and Due to the different decoction time and decoction methods of individuals, the curative effect cannot be fully guaranteed; 2. The dosage is large, and the dosage form prepared by decoction or direct crushing contains active components and ineffective components. The dosage is large and cannot reach The effect of treating specific diseases, and may produce toxic and side effects; 3. The use of modern separation and purification technology to obtain monomer compounds has low yield and high cost, and it is difficult to achieve large-scale and industrialization; 4. Realize the monomer compound through modern synthesis technology Compound groups are still technically difficult and costly

Abstract

The invention relates to a preparation method for extracting an edible and medicinal monomer for preventing and treating hyperuricemia and gout from Semen Cuscutae. The method comprises the following steps: crushing the Semen Cuscutae raw material, adding ethanol and heating and refluxing for crude extraction, purifying with a macroporous resin column, detecting and analyzing an eluant by thin layer chromatography, collecting an eluant with a high-proportion target compound and merging, and making the eluant into the product. Semen Cuscutae contains a phenylpropanoid compound. The monomer of the invention is composed of a bistetrahydrofuran ring connecting with glycosyl, has good dissolvability in medium polar solvents, such as n-butanol, ethyl acetate, etc., and has certain water solubility. According to the invention, 60% ethanol is used for decoction extraction, polar macroporous resin is used for purification, and a target monomeric compound group is purposefully enriched. The method is low-cost, has high yield, and is easy for realization of industrialization and mass production. Capsules, tablets, health-care medicinal tea, etc. prepared from the above product are convenient to use and have diversity.

Description

Technical field [0001] The invention relates to a preparation method of a medicinal and food dual-purpose monomer, in particular to a preparation method of extracting a medicinal and food dual-purpose monomer from a dodder seed for preventing and treating hyperuricemia and gout. Background technique [0002] There are many reports on the treatment of hyperuricemia and primary gout with traditional Chinese medicine. In clinical practice and daily life, people have found some effective single Chinese medicines that can treat hyperuricemia, and the active ingredients and pharmacological effects of many of them have been clarified. Such as vine, Qin Pi, Bai Ai, Artichoke, Wei Lingxian, Plantago Seed, Cork, Lysimachia, Gentiana, etc. have a certain effect of lowering uric acid [1,2] . Studies have shown that Epimedium, Coix Seed, Alisma, Plantago, Gentiana can increase the excretion of uric acid, and Gentiana can also increase the dissolution of uric acid; Eupatorium and Angelica can...
