Objective: To establish a HPLC method for the determination of emodin and chrysophanol in yixinkangtai capsules. Method: Hypersil-ODS2 C18 (4.6 mm × 250 mm
5 μm) column was used with methanol -0.1% phosphoric acid (80∶20) as mobile phase; the detection wavelength was at 254 nm
flow rate was 1 mL·min-1
column temperature 20 ℃
injection volume was 10 μL. Result: The linear range of emodin and chrysophanol was 0.04-0.80 mg·L-1 (r=1.000 0) and 0.110 2-2.204 mg·L-1 (r=1.000 0) respectively.The average recovery was 99.5% with RSD 1.81% and 99.1% with RSD 1.80% respectively. Conclusion: The sample preparation method is simple
