Production process for extracting chenodeoxycholic acid from chicken bile

The invention provides a production process for extracting chenodeoxycholic acid from chicken bile. The production process comprises the following steps: S1, preparing materials in a gall bladder room; s2, saponification treatment; s3, acidizing treatment; s4, decoloring; s5, degreasing; s6: salifying; S7: salifying; distilling, filtering and washing; s8, recrystallization: color removal: removing colored impurities again; s9, removing barium: changing barium salt into calcium salt and changing chenodeoxycholic acid barium into chenodeoxycholic acid calcium; s10, acidifying a finished product: decalcifying, and changing calcium chenodeoxycholate into chenodeoxycholic acid; and S11, drying, packaging and warehousing: drying, crushing, mixing and packaging. The saponification temperature is increased to 120 DEG C, the reaction is accelerated, the reaction time is shortened, and the technological process time is shortened. Meanwhile, time is shortened, and a large amount of energy is saved. 本发明提供了一种鸡胆汁中提取鹅去氧胆酸的生
