【摘要】 目的:建立快速鉴别香附及其伪品天葵子的方法。方法:采用衰减全反射傅里叶变换红外光谱(ATR-FTIR)技术获得香附及天葵子的红外光谱,对其进行分析,并用聚类分析法对不同炮制方法(烘、蒸、煮)所得到的香附及天葵子进行进一步分析。结果:香附及天葵子的红外光谱吸收峰位、峰强有较大的区别。聚类分析结果表明,同一种中药材经不同方法炮制后的结构信息基本一致,所含化学成分具有一定的相似性。结论:该方法快速、简单、特征性强,可用于对香附及天葵子进行快速鉴别。更多还原

【Abstract】 OBJECTIVE: To establish the method for rapid identification of Cyperus rotundus and counterfeit product Semiaguilegia adoxoides. METHODS:The IR spectrum of C. rotundus and S. adoxoides were obtained by ATR-FTIR;C. rotundus and counterfeit product S. adoxoides prepared by different processing methods(baked,steamed,boiled)were further analyzed by cluster analysis. RESULTS:There were large differences from the infrared absorption peak position and intensity of C. rotundus and S.adoxoides. The results of cluster analysis showed that same kind of Chinese medicinal materials processed by different methods showed same structure and similar chemical structure. CONCLUSIONS:The method is rapid,simple and characteristic,and can identify C.rotundus and S. adoxoides rapidly.更多还原
