中药材砂仁品种复杂,混淆品较多。为了保证中药处方和制剂的疗效,我们以化学成分为依据,利用薄层层析法对收集到的11种砂仁及混淆品进行了鉴别试验。并以香砂养胃丸为例进行了砂仁的检出试验。结果表明:正品砂仁与混淆品的区别是,前者在薄层图谱中可显出乙酸龙脑酯(Bornyl acetate)和龙脑(Borneol)两个桔红色斑点,R_f值分别为0.75和0.2。后者则无此特征,由此应用于复方制剂正品砂仁的检出,结果较为满意。本方法简单,宜于基层应用。
The variety of Amomum vulgare L In order to ensure the efficacy of Chinese medicine prescriptions and preparations, we used thin layer chromatography to conduct a discriminative test on the 11 types of amenorrhea and adulterants. Taking Xiangsha Yangwei Pill as an example, the detection test of Amomum villosum was carried out. The results show that the difference between the authentic Amomum villosum and the adulterants is that the former can show two orange-red spots of Bornyl Acetate and Borneol in the thin layer map, and the R_f values are 0.75 and 0.2, respectively. The latter did not have this feature, which was applied to the detection of the authentic Amomum villosum of the compound preparation. The results were satisfactory. This method is simple and suitable for primary applications.
