Objective:To explore the HPLC method determination of the content of uncaria rhynchophylline and isorhynchophylline for active ingredients of Chinese medicine. Method:The column Lichrospher C18(4.0×250 mm, 5μm),mobile phase:methanol:water(containing 10 mmol/L triethylamine,acetic acid adjusted to pH 7.4 to 7.6)=55:45,the detection wavelength was 254 nm,adding 10μL of 1%hydrochloric acid as a modifier. Temperature was 25℃, and the rhynchophylline and isorhynchophylline linear relationship equation was measured. Result:Rhynchophylline with isorhynchophylline regression equation was Y=9.2×104-0.281×104,Y=7.6×104-0.375×104,the linear ranges was 0.100-1.60 μg/mL(r=0.9999),0.211-1.379 μg/mL(r=0.9998). Conclusion:HPLC in the determination of the content of two components of Chinese medicine Uncaria is simple,rapid,precision and stability,can be used to control the quality of herbal medicines Uncaria.
