Abstract:
Objective To establish the quality standard for Jinyin Lidan Oral Liquid. Methods Artemisiae Scopariae Herba, Taraxaci Herba, Aurantii Fructus and Schisandrae Chinensis Fructus in Jinyin Lidan Oral Liquid were identified by TLC. The contents of naringin and neohesperidin were determined by HPLC. The HPLC separation was performed on Phenomenex C18 column (4.6 mm × 250 mm, 5 μm) with the mobile phase of methanol-0.1% phsophonic acid solution and gradient elution. The UV detection wavelength was 254 nm;flow rate was 1.0 mL/min;column temperature was 25 ℃. Results The results of TLC showed that relevant spots were clear, with strong specificity, without interference of negative sample. The calibration curves for naringin and neohesperidin were in good linearity in the range of 0.56-5.60μg (r=0.999 9) and 0.38-3.80μg (r=0.999 8), respectively. The average recoveries were 99.86%and 98.95%with RSD of 2.04%and 2.45%, respectively. Conclusion The qualitative and quantitative determination method is simple, accurate and reliable, with good stability and reproducibility, and can be used for the quality control of Jinyin Lidan Oral Liquid.
