Studies on Bear Gall. IV. On the Free Amino Acids in Bear Gall and the Related Crude Drugs

Abstract

Free amino acids in " bear gall" and the related crude drugs were determined by aminoacid analyzer (Hitachi Model KLA-3B). On the basis of these data, "bear galls" were divided into two groups with respect to the patterns of amino acids contained, and the pattern of amino acids in each group was characteristic and distinctive from those of domestic hog, bovine, and wild boar galls. The glycine/taurine ratios in these galls were significantly correlated to the ratios of glycine- and taurine-conjugated bile acids.
