A high‐performance liquid chromatographic (HPLC) method was developed for the analysis of the stilbene, oxyresveratrol. This method involves the use of a Luna® C 18 column with ultraviolet detection at 320 nm. The mobile phase consisted of acetonitrile, water and formic acid (30 : 70 : 0.04 v/v) with a flow rate of 0.6 mL/min. The calibration curves were linear over the range of 0.5–100.0 μg/mL. The mean extraction efficiency was between 98.9 and 109%. The precision of the assay was 0.069–18.4% (RSD%), and within 20% at the limit of quantitation (0.5 μg/mL). The bias of the assay was <15% and within 15% at the limit of quantitation. This assay was successfully applied to pre‐clinical pharmacokinetic samples from rat urine and to nutraceutical product analysis. Copyright © 2009 John Wiley & Sons, Ltd.
