  • Title: Analysis of the bioactive constituents of ChanSu in rat plasma by high performance liquid chromatography with mass spectrometric detection.
    Author: Xia X, Jin H, Yan S, Zhang W.
    Journal: J Pharm Biomed Anal; 2010 Nov 02; 53(3):646-54. PubMed ID: 20570458.
    Abstract:
    A plasma pharmacochemistry analysis of the bioactive constituents in rat plasma after oral administration of ChanSu was performed. High performance liquid chromatography coupled with the electrospray ionization mass spectrometry techniques of HPLC/ESI-IT-MS/MS and RRLC/ESI-Q-TOF-MS were used for the chemical profiling of samples of dosed plasma, control plasma and ChanSu extract. Comparative analysis of the resulting chemical profiles revealed 20 prototype compounds and 4 metabolites derived from ChanSu as potential bioactive components. By MS/MS analysis and accurate molecular weight assessments, the majority of these bioactive components (19 prototype compounds and 2 metabolites) were structurally identified. Moreover, seven were confirmed by comparing their retention behaviors using MS and MS/MS analysis. This study proposes a series of potential bioactive components of ChanSu, which we hope will lead to new drug discovery based on ChanSu and other traditional Chinese medicines.
