Problems solved by technology

However, people have been cutting down a lot of horse chestnuts for a long time, resulting in less and less existing medicinal resources, and now the content of medicinal resources has also dropped a lot, and the content of the best raw materials is only about 7-8%. In the prior art, there are problems of limited resources of raw medicinal materials and low content of aescin, which have always been problems for scientific researchers.

Abstract

The invention provides a preparation method of aescin. According to the invention, the fruit of horse chestnut is adopted as a raw material, and is subjected to crushing, extracting, concentrating, resin absorbing, and impurity eluting, such that aescin is obtained. Compared with prior arts, the method provided by the invention is simple and is easy to operate. Aescin content in first-time extraction can be higher than 20%, and the aescin content in the entire extraction process is gradually improved. After final extraction, the content can be higher than 88%. According to the invention, aescin extraction is carried out with limited raw material source, and a problem of low aescin content is solved. The method is suitable for industrialized productions.

Description

technical field [0001] The invention relates to a preparation method of aescin. Background technique [0002] Aescin is the fruit extract of Aesculus aesculus. It has anti-tissue edema, reduces vascular permeability, prevents water accumulation in tissues, and quickly eliminates the heavy feeling and pressure caused by local edema. It can treat stomach cold pain, abdominal fullness, malnutrition, malaria, and dysentery. However, people have been cutting down a lot of horse chestnuts for a long time, resulting in less and less existing medicinal resources, and now the content of medicinal resources has also dropped a lot, and the content of the best raw materials is only about 7-8%. In the prior art, there are problems of limited resources of raw medicinal materials and low content of aescin, which have always been problems for scientific researchers. Contents of the invention [0003] The present invention proposes a method for preparing aescin, which solves the deficien...
