The present disclosure provides methods of preparing cholic acid, deoxycholic acid, or chenodeoxycholic acid, an ester thereof, or a pharmaceutically or cosmetically acceptable salt thereof, and novel and useful synthetic intermediates, for example, as described for methods 1, 1A, 1B, 2, 3, 3A, and 4. The method can start with a plant derived steroid as a starting material, such as dehydroepiandrosterone (DHEA) or Acetyl-dehydroepiandrosterone (Ac-DHEA). Also provided are pharmaceutical or cosmetic compositions and uses thereof, which comprise one or more of cholic acid, deoxycholic acid, or chenodeoxycholic acid, an ester thereof, or a pharmaceutically or cosmetically acceptable salt thereof, which is of high purity, for example, free of animal derived impurities.

Provided is a ultra-high-sensitivity assay in which the assay can be made on a commonly used assay apparatus such as an absorptiometer and a plate reader or with naked eyes. The high-sensitivity assay in which the assay can be made on a commonly used assay apparatus or with naked eyes can be provided by combining an enzyme cycling method using thio-NAD(P) as a coenzyme, a labeling enzyme and a substrate for the labeling enzyme optimally, and by amplifying thio-NAD(P)H, which is a signaling substance, exponentially and then quantifying the thio-NAD(P)H colorimetrically.
