Untargeted metabolomics reveal the corrective effects of scorpion on epileptic mice.

Scorpion is a commonly used drug in traditional Chinese medicine for treating epilepsy, although the exact mechanisms are not yet fully understood. This study aimed to compare the treatment effects of Scorpion water extract (SWE) and Scorpion ethanol extract (SEE) on mice with pentetrazole-induced epilepsy and investigate the possible mechanisms through metabolomics methods. A pentetrazole-induced epileptic mice model was used to assess the corrective effects of SWE and SEE.

Chemical Profiling, Quantitation, and Bioactivities of Ginseng Residue.

Ginseng residue is a by-product stemming from the commercial extraction of ginsenosides. To assess the disparities between ginseng residue and ginseng tablet, we employed the ultra-high-performance liquid chromatography-quadrupole time-of-flight/mass spectrometry (UPLC-Q-TOF/MS) technique for sample analysis. The analyses revealed the presence of 39 compounds in both ginseng residue and ginseng tablets.

Comparison of IDA, SWATH, and MS techniques in the analysis of compounds of Huangqi Guizhi Wuwu decoction by UHPLC-Q-TOF-MS.

Huangqi Guizhi Wuwu decoction (HGWD) is an effective traditional Chinese medicine prescription, which is used for treating blood arthralgia in the clinic. However, its material basis has not been studied yet. Herein, a new and highly sensitive ultra-high-performance liquid chromatography-quadrupole-time of flight-MS (UHPLC-Q-TOF-MS) technique is proposed and used for the high-resolution and accurate identification of the material basis of HGWD.
