Abstract

Certain bile acids find use in the pharmaceutical industry. In view of the wide distribution of serious diseases such as HIV, AIDS and Bovine Spongiform Encephalopathy (BSE) it is desirable to avoid—as far as practicable—to have any components of animal origin in medicaments in order to eliminate any danger of infection. The present invention relates to a method of providing bile acids from non-animal starting materials.
