A rapid and simple high-performance liquid chromatographic (HPLC) method has been developed and validated for determination of scopoletin in rat plasma using psoralen as internal standard. Chromatographic separation was achieved on a C18 column using methanol and distilled water (49:51, v/v) containing 0.05% (v/v) phosphoric acid as mobile phase. The UV detector was set at 345 nm. The calibration curve was linear over the range of 0.165–9.90 μg/ml with a correlation coefficient of 0.9994. The recovery for plasma samples of 0.165, 1.32 and 6.60 μg/ml was 93.2%, 95.9% and 95.5%, respectively. The RSD of intra- and inter-day assay variations was less than 6.7%. This HPLC assay is a precise and reliable method for the analysis of scopoletin in pharmacokinetic studies.
