Abstract: | Objective To establish an HPLC method for Simultaneous content determination of dan phenol, paeoniflorin and peach kernel in guizhifuling capsule. Methods The content of dan phenol, paeoniflorin and peach kernel in guizhifuling capsule was determinated by HPLC method. The chromatographic condition was C18 column; the mobile phase was methanol-water (55∶45)elution; the flow rate was 1.0ml·min-1; the detection wavelength was 274nm; the column temperature of 30℃; the sample volume was 10μl. Results The linear range were 0.198~3.166μg(r=0.9998), 0.195~3.128μg(r=0.9996), 0.197~30158(r=0.9997)respectively. The average sample recovery rate was 99.81%(RSD=2.48%),99.69% (RSD=1.47%), 99.79%(RSD=2.12%) respectively. Conclusion The established methods is simple by this research, the results is stable and reliable, and can be used for the quality control of guizhifuling capsule. |
