A UPLC-MS-based metabolomics approach to reveal the attenuation mechanism of Caowu compatibility with Yunnan Baiyao

Abstract

Yunnan Baiyao (YNBY) is a well-known traditional Chinese medicine containing Caowu (Aconiti kusnezoffii radix, CW). However, the application of YNBY is limited by the toxicity of CW. Notably, CW is not used alone in YNBY, but is combined with other herbs in a formula for clinical use. In the present study, the compatibility of the protective effects and mechanism of YNBY with the potential toxicity of CW was investigated. After combining with other compatible herbs, the serum metabolic disorder induced by CW can be regulated. Using UPLC-MS-based metabolomics, 63 endogenous serum metabolites were identified as being associated with the potential toxicity of CW, 17 of which were regulated to normal levels when CW was combined with other compatible herbs in YNBY. These regulated metabolites were closely related to glycerophospholipid metabolism, glycosylphosphatidylinositol (GPI)-anchor biosynthesis, tyrosine metabolism, and primary bile acid biosynthesis metabolic pathways. This study aims to evaluate the attenuation mechanism of CW compatibility with YNBY.

The Effect of Simvastatin on Gut Microbiota and Lipid Metabolism in Hyperlipidemic Rats Induced by a High-Fat Diet

“…Our data show that SIM could sharply down-regulate the hepatic GCDCA level, indicating a beneficial effect against the hepatotoxicity of GCDCA. TDCA is a main bioactive substance in animal BAs that is found to have the potential of anti-inflammatory activity (Ren et al, 2019). Prior investigation reported that TDCA might significantly inhibit acute myocardial infarction and chronic inflammation by activating protease cascades to induce apoptosis (Mao et al, 2018).…”

Exploring the pharmacological effects and potential targets of paeoniflorin on the endometriosis of cold coagulation and blood stasis model rats by ultra-performance liquid chromatography tandem mass spectrometry with a pattern recognition approach

“…Biomarkers have become an integral part of the research on diseases. [54][55][56][57][58][59] In this study, it was found that PF regulated 10 biomarkers by the metabolic pathways of phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine metabolism, and tryptophan metabolism, to achieve a certain therapeutic effect. Although the systematic metabolic analysis was used in our study, we can integrate the physiological indicators and pathological observations to improve this study.…”

Mass spectrometry-based metabolomics in health and medical science: a systematic review

“…Ren et al performed MS-based metabolomics to study the toxic effects of Yunnan Baiyao on normal rats. 86 According to the results of the study, the toxicity of Aconiti kusnezoffii radix was observed earlier than in histopathology. Moreover, by comparing the changes in metabolite callback under the action of Aconiti kusnezoffii radix, processed Aconiti kusnezoffii radix, Yunnan Baiyao and Yunnan Baiyao lacking Aconiti kusnezoffii radix, with a secondary focus on metabolic pathways, the key metabolic pathways that may play a role in attenuation were determined.…”
