目的 :探讨某些中药材中有效成分在一定温度下能够升华的性质。根据升华物的结晶形状、颜色来鉴别中药材的真伪及品质的优劣。方法 :利用微量升华法得到升华物 ,在显微镜下观察结晶形状、颜色。并滴加适当化学试剂 ,观察其反应 ,来确定某些中药材的鉴别特征。结果 :对不同来源 ,不同药用部分的中药材 ,可根据其中升华物的特征来确定化学成分是否相同。结论 :微量升华得到的结晶物。为确定中药材的真伪及质量的优劣提供了可靠的依据。
Objective: To investigate the properties of active ingredients in certain Chinese herbal medicines that can sublime at a certain temperature. According to the crystal shape and color of the sublimate, the authenticity and quality of the Chinese medicinal material are identified. Method : The sublimation product was obtained by the micro-sublimation method, and the crystal shape and color were observed under a microscope. And add appropriate chemical reagents, observe the reaction, to determine the identification characteristics of certain Chinese herbal medicines. Results: For different sources, different medicinal parts of Chinese herbal medicines, according to the characteristics of the sublimate matter to determine whether the chemical composition is the same. Conclusion : Traces of sublimate crystals obtained. To determine the authenticity and quality of Chinese herbal medicines provide a reliable basis for the pros and cons.
