Direct Manufacturer 81-25-4 low price Cholic acid  immediately delivery

The bile was extracted from domestic animals (pigs, cattle, sheep, rabbits).
method 1. Preparation of crude cholic acid of cattle and sheep by ethanol crystallization method bile of cattle or sheep was taken, 100g/L sodium hydroxide was added, and heated and boiled for 12-18H to obtain saponification solution. After cooling, add acid to adjust pH 1, precipitate cholic acid, take out the cholic acid, boil, rinse, dry at 75 ℃, grind powder to obtain crude cholic acid of cattle and sheep. Preparation of crude cattle and sheep cholic acid [NaOH]→[100 ℃, 12-18H] Saponification solution [H2SO4]→[pH1, 75 ℃] crude cattle and sheep cholic acid preparation of finished products of cattle and sheep cholic acid crude cholic acid, 0.5-1 times the amount of 95% ethanol was added, heated to reflux until the solid dissolved, and cooled. The crystals were triturated, filtered and washed with 95% ethanol until the filtrate was colorless. Crystallization plus 4 times the amount of ethanol, plus 100-150g/L activated carbon, heated reflux to dissolve the crystal, hot filtration, filtrate concentration to the original volume of 1/4, cooling, crystallization, filtration, the product of cholic acid of cattle and sheep was obtained by washing and crystallizing with ethanol and drying. Crude bovine and goat cholic acid [ethanol, activated carbon] → refined solution [below 90 ℃] → bovine and goat cholic acid finished product method 2. Preparation of crude porcine cholic acid by ethyl acetate separation method fresh porcine bile was taken, add 3-3.5 times the amount of saturated lime water supernatant with stirring, continue to stir for 5-10min after adding, heat to boiling for 2min, cool, filter, add hydrochloric acid to adjust pH 3.5, precipitate, stand for more than 12h, crude cholic acid was obtained. Take it out, wash it with water, add 1.5 times sodium hydroxide, add 9 times water, heat and boil for 12-18H, let it cool, and let it stand overnight to get paste. Water was added, and sulfuric acid was added to adjust pH to 1 to precipitate hyocholic acid. Take out, mash, rinse to no acid, and filter to get crude hyocholic acid. $pig bile [saturated lime water] →[100 ℃, pH11-12] Alkaline filtrate [HCl]→[pH3.5] crude cholic acid [water, naOH] → paste [H2SO4]→[pH1] Preparation of crude hyocholic acid; Take crude hyocholic acid, add 4 times the amount of ethyl acetate, add 150-0.5g/L activated carbon, refluxed for h, let to cool and filter, the filter cake is treated once with 1.5-2.5 times ethyl acetate, and the filtrates are combined twice. 200g/L anhydrous sodium sulfate was added, allowed to stand overnight, concentrated to 1/3 of the original volume, released, cooled to crystallize, filtered, the crystals were washed with ethyl acetate, and dried to obtain a final product of hyocholic acid. Crude hyocholic acid [ethyl acetate, activated carbon] → filtrate [anhydrous sodium sulfate] → filtrate [concentration] → Product of hyocholic acid.
