Abstract:
Objective To establish an HPLC method for the determination of anthraquinones including rhein, emodin and chrysophanol in xinshenyan capsules. Methods Anthraquinones were determined by HPLC with Phenomenex-C18 column (250 mm×4. 6 mm, 5 μm) as the chromatographic column and methanol-1% acetic acid (70:30) as the mobile phase. The flow rate was 1. 0 mL·min-1 and the detection wavelength was set at 254 nm. Results The liner range of rhein, emodin and chrysophanol was 4. 96-24. 80 μg·mL-1(r=0. 999 6), 6. 58-32. 91 μg·mL-1(r=0. 999 9) ,and 15. 11-75. 55 μg·mL-1 (r=0. 999 9),respectively, and the average recovery was 100. 78%, 98. 13% and 99. 29%, respectively. Conclusion The method is simple and practical, the result is accurate and reliable and it can be used to determine the contents of rhein, emodin and chrysophanol in xinshenyan capsules.
