Extraction of bilirubin with hydrochloric acid from the crude drug, oriental bezoar, obtained from the gall bladder of cattles, was examined. A suitable concentration of hydrochloric acid for the extraction was 5-10% and 7.5% hydrochloric acid was used. The content of bilirubin in oriental bezoar was measured by Heilmeyer-Krebs' method. A concretion from Australia had the highest concentration of bilirubin among the several kinds examined.
