- •
An optimized solid phase extraction method was built to concentrate and purify the analytes in rat urine.
- •
HPLC–DAD–ESI–TOF/MS combined with HPLC–ESI–QqQ/MS was adopted to separate and identify the metabolites of
- •
25 parent compounds and 28 metabolites, especially two new metabolites were identified.
- •
Urine samples collected at different time period were screened to investigate the dynamic metabolic process of
