Problems solved by technology

However, on the one hand, due to the different sources of ox bile, the content of bound bile acids in ox bile is quite different, and the ox bile that can meet the technical requirements of cultivating bezoar in vitro is limited, and the resources of ox bile cannot be fully utilized.
On the other hand, it is necessary to control the difference of finished products within a reasonable range, which leads to more control links in the industrial production process, and the control process is more cumbersome.

Abstract

The invention discloses an in-vitro cultivated calculus bovis and a preparation method thereof. Fresh fel bovis is used as a raw material, and conjugated bile acid (taurocholic acid, glycocholic acid,taurodeoxycholic acid and glycodeoxycholic acid) with a high purity is obtained by utilizing a modern separation technology. By carrying out technical promotion on an industrialized in-vitro cultivated calculus bovis process and adding the high-purity conjugated bile acid in the cultivation link, the finally prepared in-vitro cultivated calculus bovis finished product not only conforms to the quality standard, but also has total content of the conjugated bile acid of over 4%, is stable in quality, and has basically consistent quality with high-quality natural calculus bovis.

Description

technical field [0001] The invention belongs to the technical field of in vitro cultured bezoar, and in particular relates to a process for producing in vitro cultured bezoar by using modern separation techniques to obtain combined bile acids and in vitro cultured bezoar. Background technique [0002] Bezoar is bovine gallstones. Bile acids are one of its various active ingredients. Bile acids are divided into bound bile acids and free bile acids. Among them, bound bile acids such as taurocholic acid, glycocholic acid, and taurodeoxy Cholic acid and glycodeoxycholic acid have pharmacological effects such as antibacterial and anti-inflammatory, and their content is one of the important indicators to distinguish high-quality or inferior bezoar. [0003] Natural bezoar is a naturally formed product, and there are unavoidable differences in quality, and its combined bile acid content also has a large difference. Contents are shown in Table 1). However, the sources of high-qual...
