Abstract

Fresh and desiccated gall bladders of the Ursidae family (bears) obtained as criminal evidence were characterized by analysis of the principal biliary components, mainly ursodeoxycholyl-taurine, cholyl-taurine and chenodeoxycholyl-taurine using TLC and HPLC. This bile acids profile appears to be an Ursidae family characteristic. Results show that of the samples from Asia only 3% were from the Ursidae family and 18% were from "farmed bears." Samples seized in the U.S.A. and Canada showed that 22.6% and 85% respectively, were from Ursids. The remaining samples were consistent with bile from the domestic pig (Suidae).

摘要

作为刑事证据获取的熊科（熊）新鲜和干燥胆囊，通过使用薄层色谱法（TLC）和高效液相色谱法（HPLC）分析主要胆汁成分，主要是熊去氧胆酰牛磺酸、胆酰牛磺酸和鹅去氧胆酰牛磺酸来进行表征。这种胆汁酸谱似乎是熊科的一个特征。结果表明，来自亚洲的样本中只有3%来自熊科，18%来自“养殖熊”。在美国和加拿大查获的样本显示，分别有22.6%和85%来自熊科动物。其余样本与家猪（猪科）的胆汁一致。
