Abstract
An HPLC method for the simultaneous determination of six active ingredients present in famous Chinese clinical prescription has been established. HPLC conditions included Agilent Hypersil-C18 column (4.6 mm × 250 mm, 5 μm) and the mobile phase was a mixture of acetonitrile and 0.1 % phosphoric acid for gradient elution. The flow rate was 1.0 mL/min and the column temperature was at 30 ºC. Six active ingredients had good linear relationships: berberine in the range of 0.0081-0.4045 μg (R2 = 0.9997), aloe-emodin in the range of 0.0076-0.3820 μg (R2 = 0.9999), rhein in the range of 0.0104-0.5175 μg (R2 = 0.9998), emodin in the range of 0.0122- 0.6110 μg (R2 = 0.9999), chrysophanol in the range of 0.0214-1.0690 μg (R2 = 0.9999) and physcion in the range of 0.0057-0.2830 μg (R2 = 0.9994). Their average recoveries were 104.73 % (RSD = 1.6 %), 95.19 % (RSD = 2.3 %), 104.31 % (RSD = 2.0 %), 101.72 % (RSD = 2.7 %), 95.50 % (RSD = 2.2 %) and 103.08 % (RSD = 2.7 %), respectively. This method was steady with high precision and good repeatability and could be used for the determination of the six active ingredients and quality control of Sanhuang tablet.
