熊胆为贵重中药材,来源于熊科动物棕熊Ursus arctos L或黑熊Selenarctos thibetanusCuvier或其近缘动物的干燥胆。中华人民共和国卫生部进口药材部标准(WS_4-11-86)对熊胆的TLC鉴别采用硅胶G制板,展开剂中用异戊醚,显色剂用30％硫酸溶液,其层析效果的重现性,分辨率受层析条件的限制,尤其硫酸有腐蚀性,硅胶G板较软,点样、展层,喷显色剂等操作时均需十分小心。受限制较大。为了克服以上缺点,笔者采用硅胶G+0.2％CMC-Na铺板,展开剂中以常规试剂乙醚代替异戊醚,并喷以10％磷钼酸乙醇溶液显色,对熊胆进
Bear bile, a precious Chinese herbal medicine, originates from Ursus arctos L or dry gut of Selenarctos thibetanus Cuvier or its close relatives. The Ministry of Health of the People’s Republic of China (WS_4-11-86) has adopted the silicone G-plate for the identification of bear gall bladder, the isoamyl ether is used as the developing agent, and the 30% sulfuric acid solution is used as the coloring agent. Reproducibility, resolution is limited by the chromatographic conditions, especially sulfuric acid is corrosive, silica gel G-plate is soft, and the operation of spotting, layering, and ejecting coloring agent must be very careful. Restricted. In order to overcome the above drawbacks, the author used silica gel G + 0.2% CMC-Na plating, developing reagents with conventional reagents ether instead of isoamyl ether, and sprayed with 10% phosphomolybdic acid ethanol solution color, the bear bile
