Objective To develop an HPLC method for simultaneous determination of the eleven constituents (agaric-alcohol, naringin, hesperidin, neohesperidin, honokiol, emodin, magnolol, costunolide, dehydrocostus, chrysophanol, and physcion) in Chenxiang Huazhi Pills (CHP) by HPLC with gradient elution. Methods The chromatographic separation was performed on an Thermo Syncronis C₁₈ column (4.6 mm×250 mm, 5 μm) which was operated at 30℃. The mobile phase was a linear gradient prepared from water (A) and acetonitrile (B). The linear gradient elution program was programmed as follows:0-10 min, 20% acetonitrile; 10-20 min, 20%-40% acetonitrile; 20-24 min, 40% acetonitrile; 24-26 min, 40%-52% acetonitrile; 26-30 min, 52% acetonitrile; 30-31 min, 52%-90% acetonitrile; 31-35 min, 90% acetonitrile; 35-40 min, 90%-100% acetonitrile; 40-43 min, 100% acetonitrile; 43-45 min, 100%-20% acetonitrile. The flow rate was 1 mL/min and the detection wavelength was 215 nm. Results The analysis permitted very good separation of eleven constituents within 43 min. A good linear relationship between the peak area and the injection volume was obtained. The ranges of the eleven constituents were 1.4-13.6, 10.0-200.0, 31.5-315.0, 1.0-120.1, 1.8-50.6, 0.93-10.1, 1.8-30.0, 0.2-40.3, 1.8-18.1, 1.7-25.0, and 0.45-10.70 μg/mL. The average recoveries of eleven constituents in the samples were in the range of 98.90%-100.87%. The precision RSD of the peak areas of the 11 components ranged from 0.55%-1.54%; Eleven components had good stability within 30 h, and the concentration RSD of each component ranged from 0.75% to 1.94%; The repeatability RSD of each component ranged from 0.39% to 1.73%. The content of agaric-alcohol, naringin, hesperidin, neohesperidin, honokiol, emodin, magnolol, costunolide, dehydrocostus, chrysophanol, and physcion in six batches were 92.0-201.0, 511.5-9 033.0, 5 475.0-12 635.5, 54.5-5 095.5, 192.0-2 137.5, 117.0-391.5, 106.5-1 281.5, 13.0-136.5, 93.5-199.0, 177.0-1 207.0, and 33.5-251.5 μg/g, respectively. Conclusion The method is accurate, rapid and simple with high sensitivity, precision and repeatability, which has been successfully applied as an effective tool for the multicomponent analysis of CHP.
