A method for purifying chenodeoxycholic acid isolated from the bile goose

The present invention provides a method of separating and purifying cholic acid from chenodeoxycholic goose bile, bile particularly fresh saponification geese, Shenyang calcium, bold, Macroporous chenodeoxycholic acid to give pure product. The present invention has the following advantages: 1) expanding the raw material source of chenodeoxycholic acid, cholic acid provides a method of separating and purifying chenodeoxycholic from goose bile; 2) as compared with the conventional extraction process, the use of acetic acid no longer ethyl, increasing the reproducibility of the experiments, reduce environmental pollution and improve the recovery of chenodeoxycholic acid; 3) than the other extraction methods macroporous resin, the operation is simplified, improving the chenodeoxycholic acid Recovery rate.
