In vivo metabolism study of Polygalic acid in rat using HPLC-ESI-MSn
Biomed Chromatogr 2012 Feb;26(2):220-4.PMID:21618563DOI:10.1002/bmc.1650
A very simple and direct method has been established for the determination of Polygalic acid and its metabolites in rat urine based on HPLC coupled with electrospray ionization multi-stage tandem mass spectrometry (HPLC-ESI-MS(n)). The rats were administered a single dose (100 mg/kg) of Polygalic acid by oral gavage. The urine samples were collected and purified through a C(18) solid-phase extraction cartridge, and then these pretreated samples were injected into a reversed-phase C(18) column with a gradient elution program, whereas acetonitrile-0.5% aqueous formic acid was used as mobile phase and detected by an on-line MS/MS system. As a result, the parent drug and its four metabolites were identified and characterized in rat urine for the first time by comparing their changes in molecular mass (ΔM), retention times and full-scan MS(n) spectra with those of the parent drug. A possible metabolic pathway of Polygalic acid was investigated and proposed. More importantly, the results demonstrated that the newly developed method (HPLC-ESI-MS(n)) was sensitive, simple and suitable for the determination of Polygalic acid and its metabolites in biological samples.
