在近来的药检工作中,发现不少用动物(牛、羊等)胎盘或其他的物质制造的紫河车伪品以及经提取过的紫河车劣品。这些伪劣品在临床上不但没有紫河车应有的疗效,则且对人体产生危害。鉴于此,本文采用薄层层析法并结合紫河车的性状对它进行了真伪鉴别,取得了满意的效果。 1 实验材料 1.1 仪器:BT—2薄层涂布器:(武汉市新华分析仪器厂);二用紫外线分析仪:(上海顾村电光仪器厂)。 1.2 试剂:硅胶G:(青岛海洋化工厂);三氯甲烷、丙酮等均为分析纯。 1.3 试样:对照组 紫河车药材1系自行收集的健康
In the recent drug inspection work, a lot of counterfeit products of the Placenta made of animal (cattle, sheep, etc.) placenta or other substances were found, as well as the defective products of the Placenta that were extracted. These fake and inferior products are not only clinically ineffective in the effects of the Placenta, but also cause harm to the human body. In view of this, this paper uses the thin layer chromatography combined with the traits of Placenta to identify it and obtain satisfactory results. 1 Experimental Materials 1.1 Instruments: BT-2 thin layer coating device: (Wuhan Xinhua Analytical Instrument Factory); Second-use UV Analyzer: (Shanghai Gucun Electro-Optical Instrument Factory). 1.2 Reagents: Silicone G: (Qingdao Marine Chemical Factory); chloroform, acetone, etc. are all analytically pure. 1.3 Specimen: Control Group Self-collected health of the Hopper Formula 1 system
