Abstract:
Plasma nontargeted metabolomics technology was developed for investigating the effect and mechanism of improving kidney deficient in mice of Polygoni Multiflori Radix Praeparata. Thirty-five ICR mice were randomly divided into the control group, the model group, the BB24 h (braising with black bean sauce for 24 hours) group, the BB32 h group, and the BB40 h group. Biochemical indices in blood plasma of mice were measured by collecting eye blood after modeling. Changes in plasma endogenous metabolites of mice from each group were determined by ultra-performance liquid chromatography-linear trap quadrupole-orbitrap XL (UPLC-LTQ-orbitrap XL), and differential metabolites were screened. The results of pharmacodynamic investigation showed that compared to the model group, the levels of estradiol increased obviously in the BB24 h (P < 0.05), and the levels of cortisol increased obviously in BB32 h (P < 0.05). The hormone level of mice with kidney deficiency was significantly improved after taking processed Polygonum multiflorum. A total of 70 differential endogenous metabolites in blood plasma of mice were identified from all treatment groups, which mainly involved glycerophospholipid meta-bolism, arachidonic acid metabolism, phenylalanine metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, and linoleic acid metabolism. The study indicated that Polygoni Multiflori Radix Praeparata may play the role of tonifying liver and kidney by improving the disorder of hypothalamic-pituitary-adrenal axis and regulating lipid metabolism in mice. Correlation analysis on differential metabolites in blood plasma and the chemical constituents showed that stilbene glycosides and saccharides may be the key pharmacodynamic material basis. The present study provides a new reference and theoretical foundation for revealing the potential pharmacodynamic material basis and mechanism investigation on tonifying liver and kidney of Polygoni Multiflori Radix Praeparata. This study was carried out following the ethical guidelines and regulations for the use of laboratory animals of the Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences and passed the animal experimental ethical review [No. SYXK (Jing) 2019-0003].
