Introduction: This study aims to isolate and characterize potential cytotoxic compounds from the roots of Bauhinia variegata Linn. (Caesalpiniaceae) and evaluate their activity against human cancer cell lines. Five compounds, namely β-sitosterol (1), piperine (2), piperolein B (3), retrofractamide A (4), and dehydropipernonaline (5), were isolated from B.

Ethnopharmacological Relevance: Cornus officinalis (CO) has been widely used as Chinese herbal medicine and has a good clinical efficacy in liver disease. In particular, it has a significant therapeutic effect on metabolic liver disease. However, systematic pharmacological studies on its hepatoprotective effect on non-alcoholic fatty liver disease (NAFLD) are lacking.

Currently, treatment with antiepileptic drugs (AEDs) is still the first choice for epileptic patients, while monitoring their blood concentrations is undoubtedly beneficial for minimizing their adverse side effects and optimizing their therapeutic effects. In this study, an ultra-high performance liquid chromatography coupled with tandem mass spectrometry with polarity switching was developed and validated for simultaneous determination of 14 AEDs and 2 active metabolites in human serum. Olanzapine was selected as the internal standard.

A novel dual-wavelength ultrahigh performance liquid chromatography (UHPLC) fingerprint was established, 56 common peaks were confirmed and attributed to the source of the medicinal materials, and 13 chromatographic peaks of them were identified by UHPLC quadrupole time-of-flight (Q-TOF)-MS/MS and UHPLC-UV method. Furthermore, a simple and sensitive HPLC-quadrupole trap (Q-TRAP)-MS/MS was developed for the simultaneous determination of 16 active components with electrospray ionization (ESI) source switching between positive and negative modes in a single run. The above two methods were successfully applied for the quality evaluation of Guanxinjing capsule (GXJC).
