Problems solved by technology

[0005] At present, taurocholic acid is mainly extracted from the bile of cattle, and the source of bile of cattle is relatively difficult
Simultaneously, because the bile composition of the ox and the bile of the sheep have certain difference, the impurity content such as protein is different, when the conventional ox bile extraction method is used to extract taurocholic acid from the bile of the sheep, not only the extraction rate is low, and The product contains high levels of impurities, therefore, a method suitable for the extraction of taurocholic acid from sheep bile is required

Abstract

The invention discloses a method for extracting taurocholic acid in sheep bile through a column chromatography isolation method. The method comprises the following steps: filtering, performing protein precipitation treatment, performing depigmentation treatment, salting out, extracting, dewatering concentration and performing column chromatography isolation. According to the method, the sheep bile serves as an extracting raw material, the extraction cost of the taurocholic acid is reduced, the extraction process is simple, and the income is higher. The taurocholic acid is extracted through the column chromatography isolation, the column chromatography isolation is good in purification effect, the extracted taurocholic acid does not have a fishy smell and is high in purity, the product is high in yield, the extraction process is simple, and industrial production is promoted.

Description

[0001] technical field [0002] The invention belongs to the technical field of biomedicine and relates to a method for extracting taurocholic acid, in particular to a method for extracting taurocholic acid in goat bile by a column chromatography separation method. Background technique [0003] Bile acid is the main component of medicinal bile and is a general term for various bile acids. Various bile acids are combined with glycine or taurine in the liver and secreted into the gallbladder in the form of sodium salt. Sodium glycocholate and sodium taurocholate, as the main components of bile salts, have an important relationship with the digestion and absorption of fat in the body. They can not only enhance the activity of lipase, catalyze the decomposition of fat, and increase the absorption of fat-soluble vitamins, It can also promote the secretion of bile and stimulate the movement of the small intestine. [0004] Taurocholic acid is widely found in the bile of cattle, ...
