Abstract
A HPLC method for determination of trans-resveratrol concentrations in rat plasma was developed. Plasma samples were treated with acetonitrile to deposit proteins. The analysis used a Hypersil ODS(2) C(18) column (5 microm, 4.6 mm x 250 mm) and methanol/distilled water as the mobile phase (flow-rate=1 mL/min). The UV detection wavelength was 303 nm, and chlorzoxazone was used as the internal standard. The calibration curve was linear over the range of 0.02-40 microg/mL with a correlation coefficient of 0.9997. This concentration range corresponds well with the plasma concentrations of resveratrol in pharmacokinetic studies. There was 98.7%, 91.3% and 84.4% recovery from 0.02, 0.4 and 40 microg/mL plasma samples respectively. The R.S.D. of intra- and inter-day assay variations were all less than 12%. This HPLC assay is a quick, precise and reliable method for the analysis of resveratrol in pharmacokinetic studies.Entities:
