Abstract
This study was conducted to develop simple methods for the extraction of chenodeoxycholic acid (CDCA) and synthesis of ursodeoxycholic acid (UDCA) from pig by-products. The enzymatic method, which uses bile salt hydrolase (BSH) enzymes to extract CDCA, was found to be more efficient than the chemical method. The chemical method, which uses pig by-products, resulted in UDCA amounts of 6.05 mg, 0.51 mg, 3.04 mg, and 1.26 mg in 100 g of the liver, stomach, small intestine, and large intestine, respectively. The amounts of UDCA synthesized/100 g through the chemical and enzymatic methods required to extract CDCA were 3.48 g and 2.22 g, respectively. The procedure developed in this study was simplified by three stages compared to the conventional chemical method of extracting CDCA. Moreover, this study provides a technique that improves the utilization of pig by-products.
