目的对牛蒡子药材中内果皮石细胞显微特征指数与牛蒡苷含量的相关性进行研究,从显微鉴定的角度评价其质量,为中药材“辨状论质”提供依据。方法采用容量分析的方法测定牛蒡子药材中内果皮石细胞显微特征指数,采用HPLC色谱法测定牛蒡苷的含量,对两组数据进行SPSS统计,并进行相关性分析。结果牛蒡子药材中内果皮石细胞显微特征指数与牛蒡苷含量呈负相关,且高度相关,有极显著的统计学意义。结论为牛蒡子药材的质量评价,从显微鉴定的角度给出了新的参考。
Objective To study the correlation between the microscopic index of endocarp cells and the content of arctiin in Fructus Arctii, evaluate its quality from the perspective of microscopic identification, and provide the basis for the Chinese herbal medicine. Methods The volume index was used to determine the microscopic index of endocarpus cells in Arctium lappa L., and the content of arctiin was determined by HPLC. SPSS statistics were used to analyze the data of two groups. Results The results showed that the micro-characteristics index of endocarpus stone in Arctium lappa L. was negatively correlated with the content of arctiin, and was highly correlated with the significant statistical significance. Conclusion The quality evaluation of Arctium lappa L. was given, and a new reference was given from the perspective of microscopic identification.
