Abstract

The invention discloses a method for extracting an effective component from an ethanol part of acid litchi. The method comprises the following steps: baking and crushing acid litchi, soaking in 95% ethanol for 0.2-0.4 hour, extracting for 80-100 seconds with microwave power of 400-600W, and concentrating to obtain an extract; recovering the ethanol, and dissolving the extract with n-butyl alcohol, filtering, concentrating at reduced pressure to prepare a clear extract, namely the total active component of acid litchi, and recovering the n-butyl alcohol, wherein the acid litchi is acid litchi kernels, acid litchi leaves, acid litchi stems, acid litchi barks and acid litchi fruit peels. The method has the characteristics of simple and effective extraction and purification and high extraction rate; the extract is definite in component and high in purity, and can be used for preparing preparations which have better curative effect and are convenient to take; a solvent for extraction is absolute ethyl alcohol, the step of configuring concentration is cancelled, the time is saved, and the recovered solvent can be used in other aspects. The method is economic, energy-saving and environment-friendly, is advantageous to production performance, and has good economical benefit, social benefit and ecological benefit.

Description

technical field [0001] The invention belongs to the technical field of extracting traditional Chinese medicines, and relates to a method for extracting active ingredients from ethanol parts of sour lychees. Background technique [0002] Sour litchi is a Sapindaceae plant sour litchi (Litchi Chinensis Sonn), mainly produced in Guangdong, Guangxi and other places. The effect of cold pain relief is recorded in multiple editions of "Chinese Pharmacopoeia". Active components such as polysaccharides, total saponins and flavonoids can be isolated from litchi and litchi cores. Studies have shown that litchi and litchi cores and their active components have the functions of blocking the synthesis of nitrosamines and scavenging nitrite ions, anti-oxidation and In addition to scavenging free radicals and inhibiting the biological activities of HBsAg, HBeAg and HBV-DNA, etc., it also has anti-inflammatory, analgesic, antipyretic and inhibition of transplanted tumors in mice, anti-immun...
