High performance liquid chromatography conjugated metabolites

MAE in conjunction with high-performance liquid chromatography/mass spectrometry (HPLC/MS) shortened the cleanup procedure and provided satisfactory recoveries (97-102%) for the parent imazethapyr and its two metabolites (hydroxy and glucose conjugate metabolites). [Pg.757]

The pharmacokinetics parameters of catechin metabolites are listed in table 7.2. Intact tea catechins, EC, ECG, EGC, and EGCG in human plasma and urine, are detected but with low concentrations. To determine the content of conjugated metabolites of catechins, blood and urine samples are treated with p-glucuronidase and sulfatase to remove the glucuonic or sulfate group prior to high-performance liquid chromatography (HPLC) analysis. [Pg.114]
