目的基于多指标法用于广西不同产地鸡骨草药材质量的综合评价。方法采用UV法测定醇提液中总黄酮和总皂苷的含量及对DPPH自由基的清除率,采用HPLC法测定相思子碱、下箴刺桐碱的含量,并结合相关性分析法和主成分分析法进行分析。结果总黄酮、总皂苷、相思子碱和下箴刺桐碱含量呈显著相关性;贵港产地的鸡骨草质量最优,其次为广西玉林。结论基于多指标结合主成分分析法能够客观评价不同产地鸡骨草药材的质量,为鸡骨草的质量控制和开发利用提供一定的理论依据。
Objective To evaluate the quality of Abrus cantly extract material in Guangxi based on multi-index method. Methods The content of total flavonoids and total saponins and the scavenging rate of DPPH free radicals in alcohol extraction solution were determined by UV method. The contents of acifloxacin and progesterone were determined by HPLC. Correlation analysis and principal components Analytical method for analysis. Results The contents of total flavonoids, total saponins, abscisic acid and lower acerolataine were significantly correlated. The quality of Clover was the highest in Guigang area, followed by that of Guangxi Yulin. Conclusion Based on multi-index and principal component analysis, the quality of Abrus cantoniensis in different areas can be objectively evaluated, which provides some theoretical basis for the quality control and development of Aconitum.
