Background: Bushen Huoxue Qubi (BHQ) granules, a traditional Chinese medicine preparation, has been clinically used for the treatment of the blood stasis syndrome. Objective: The main objective is to investigate whether the diseased condition would alter the pharmacokinetics and tissue distribution of tanshinone IIA in BHQ, which was given orally to the acute blood stasis rats. Materials and Methods: The main bioactive constituent in BHQ, tanshinone IIA, was measured in the plasma and tissues of animals by the high performance liquid chromatography with ultraviolet detection. The analysis was successfully performed on an Agilent TC-C 18 column (250 × 4.6 mm I.D., 5 μm) protected with a  Octadecylsilane (ODS) guard column (10 × 4.6 mm I.D., 5 μm). The mobile phase was aqueous solution (A) (containing 0.40% aqueous acetic acid) and acetonitrile (B). The conditions of the solvent gradient elution were 35-40% (B) in 0-15 min, 40-42% (B) in 15-18 min and 42-70% (B) in 18-30 min at a flow rate of 1.0 mL/min. Detection was conducted with wavelength of 270 nm at 30°C. Results: Good linearity relationships were found (r2 > 0.9955) over the investigated concentration range for bio-samples. Blood stasis was associated with significantly higher area under the concentration-time curve (AUC), the maximum plasma concentration (C max ) and biological half-life (t 1/2 ), lower total body clearance (CL) and apparent volume of distribution (Vd) of tanshinone IIA in plasma and higher AUC 0-t of tanshinone IIA in the analyzed tissues of rats treated with BHQ. Conclusion: Blood stasis could alter pharmacokinetics and tissue distribution of tanshinone IIA in BHQ.
