Objective:To investigate the spectrum-effect relationship of effect of material components in Shaoyao Gancaotang on the levels of malondialdehyde (MDA), superoxide dismutase (SOD) and adenosine triphosphatase (ATPase) in brain tissue of epileptic mice, and to reveal the material basis of the antiepileptic effect of Shaoyao Gancaotang. Method:HPLC was used to establish the fingerprint of 15 batches of Shaoyao Gancaotang, the mobile phase was consisted of acetonitrile (A)-0.1% phosphoric acid aqueous solution (B) for gradient elution (0-15 min, 19%A; 15-45 min, 19%A-50%A; 45-46 min, 50%A-90%A; 46-48 min, 90%A), the flow rate was 1.0 mL·min-1, and the detection wavelength was 237 nm. The mouse epilepsy model was induced by penicillin, the protective effect of 15 batches of Shaoyao Gancaotang on MDA, SOD and ATPase levels in brain tissue of epileptic mice was investigated. Grey correlation analysis was used to analyze the correlation between the peak areas of characteristic peaks in the fingerprint of 15 batches of Shaoyao Gancaotang and three pharmacodynamic indexes (the activities of MDA, SOD and ATPase), and the mathematical model of spectrum-effect relationship between different material components and pharmacodynamic indexes was established. Result:Shaoyao Gancaotang could increase the contents of ATPase and SOD and reduce the content of MDA in the brain tissue of epileptic mice, and most of the differences were significant (P<0.05, P<0.01). There were 28 common peaks in the fingerprint of 15 batches of Shaoyao Gancaotang, and 15 of them were characteristic peaks. Grey correlation analysis found that the characteristic peaks contributed to the activities of MDA, SOD and ATPase included peak 2 (albiflorin), peak 3 (paeoniflorin), peak 5 (liquiritin), and so on, the specific ranking was peak 3>peak 6>peak 12>peak 8>peak 2>peak 5>peak 9>peak 4>peak 10>peak 7>peak 13>peak 11>peak 15>peak 1>peak 14. Conclusion:Shaoyao Gancaotang can affect the activities of SOD, MDA and ATPase in brain tissue of epileptic mice by multi-component synergy. Simultaneously, introducing the grey correlation analysis into the correlation evaluation of the spectrum-effect relationship between components and efficacy of Chinese herbal compounds, it can objectively reflect the essence of the synergistic action of multiple components in traditional Chinese medicine (TCM), and it is an effective analysis method for screening and predicting the pharmacodynamic components of TCM.

Metabonomics delineates allergic reactions induced by Shuang-huang-lian injection in rats using ultra performance liquid chromatography-mass spectrometry / 中国天然药物

Shuang-huang-lian Injection (SHLI) is the first successfully developed drug from traditional Chinese medicine (TCM) powder for injection, since its use for the treatment of acute respiratory tract infection, pneumonia, influenza, etc. At the same time, its allergic reactions have also emerged, which limits clinical applications. However, few scholars pay attention to the mechanism of allergic reactions. In this present study, metabonomics technology was used to explore the changes in endogenous metabolites in urine of the rat model of SHLI induced allergic reaction; we and analyzed the metabolites, metabolic pathway, and the mechanism which were closely related to the allergic reactions. The levels of serum histamine and tryptase were examined and changes in histomorphology were also observed. Based on the UPLC-Q-TOF/MS metabonomics, we carried out the pattern recognition analysis, selected potential biomarkers associated with allergic reactions, and explored the pathological mechanism for SHLI induced allergic reaction, which laid the foundation for the safety research of SHLI. Our results showed that SHLI increased the levels of serum histamine and tryptase in rats with allergic reaction; we determined 15 biomarkers in rat allergic reaction model induced by SHLI and found multiple metabolic pathways involved, such as metabolism of linolenic acid, phenylalanine, amino acid, 2-oxo acid, and purine and other metabolic pathways.

Metabolomics of bovine serum albumin-induced allergic reactions based on UPLC-Q-TOF-MS / 中国中药杂志

The metabonomic techniques were used to study the changes in endogenous metabolites between urines of rats in normal physiological conditions and bovine serum albumin induced allergic reactions, identify potential biomarkers associated with allergic reactions, and then analyze the metabolic pathways and the metabolic mechanisms of allergic reactions. The bovine serum albumin-induced allergic reactions in rats were adopted as a model to detect histamine and tryptase in rat serum and observe the issue morphology of lungs and trachea in rats. UPLC-Q-TOF-MS was applied in metabonomic analysis on urines between control group and allergic reaction model group. Principal component analysis(PCA) and partial least squares discriminant analysis(PLS-DA) were applied to observe the differences in metabolic profiling between urines of the two groups and select differential metabolites. There were significant differences in metabolism spectrum between the model group and the control group. Totally 14 differential metabolites and 4 major metabolic pathways were screened out. The metabonomic research method for urines of rats with bovine serum albumin-induced allergic reactions based on UPLC-Q-TOF-MS was established in this study. It was speculated that the mechanism of bovine serum albumin-induced allergic reactions may involve biosynthesis of isoflavone and folic acid and metabolism of tryptophan, nicotinic acid and nicotinamide. It lays a foundation for further exploration of the application of metabolomics in drug allergy reaction studies.
