Material basis of kidney Yang deficiency rats before and after salt processing of Dipsacus asper based on spectrum-effect relationship
This paper aims to study the spectrum-effect relationship between the fingerprints before and after salt processing of Dipsacus asper and the efficacy of warming and tonifying kidney Yang and find the main active components against kidney Yang deficiency before and after salt processing of D.asper,so as to provide the basis for clarifying the effect of salt processing on kidney Yang deficiency.The HPLC fingerprint before and after salt processing of D.asper was established by the HPLC-DAD.15 common peaks were obtained,and 11 components were identified.The content changes of various components in rat serum were detected,and the difference in efficacy before and after salt processing was compared.The results of pharmacological experiments showed that salt processing of D.asper could enhance the kidney index.At the same dose,there was a significant difference between the raw D.asper and D.asper after salt processing groups.Compared with the model group,the contents of ACTH,cAMP,CORT,E2,GH,Na+-K+-ATPase,T,and T4 in the serum of rats in the administration group increased to a certain extent,and the contents of cGMP and TNF-α decreased to a certain extent.Among them,there were significant differences in the above indexes in the serum of rats in the high-dose group of raw D.asper,middle-dose group of D.asper after salt processing,high-dose group of D.asper after salt processing,and the positive drug group.The overall results showed that D.asper after salt processing was more effective than raw D.asper in preventing kidney yang deficiency.The efficacy of D.asper was evaluated by grey correlation analysis,entropy method,and Pearson correlation analysis,and the components of D.asper after salt processing against kidney yang deficiency were screened out.According to the results of correlation degree ranking,the components with increased ranking before and after salt processing of D.asper were loganin,chlorogenic acid,dipsacoside A,asperosaponin Ⅵ,caffeic acid,and isochlorogenic acid B.It was preliminarily speculated that these compounds may be the potential pharmacodynamic components for the treatment of kidney yang deficiency before and after salt processing of D.asper.The changing components before and after the salt processing of D.asper were determined,which proved that D.asper after salt processing was superior to D.asper in the treatment of kidney yang deficiency.The spectrum-effect relationship between the efficacy of D.asper before and after salt processing and the treatment of kidney yang deficiency was established,which laid a foundation for the subsequent study on the pharmacodynamic components and molecular mechanism of salt processing of D.asper.
