Objective: The study was conducted to establish a HPLC method for simultaneously determination of rutin
naringin
hesperidin
neohesperidin and quercetin in Jinggu tablet. Method: The separation of compounds was performed on Elite Kromasil-C18 column (4.6 mm×250 mm
5 μm)
with the mobile phase consisted of acetonitrile-0.2% acetic acid. The flow rate was set at 1.0 mL·min-1and detection wavelengths were set at 254 nm for rutin and quercetin
283 nm for naringin
hesperidin and neohesperidin. Result: The samples showed a good relationship in the ranges of 0.012 5 -0.500 4 g·L-1 for rutin
0.010 0-0.400 8 g·L-1 for naringin
0.003 3-0.032 7 g·L-1 for hesperidin
0.011 3-0.225 6 g·L-1 for neohesperidin and 0.004 1-0.081 3 g·L-1 for quercetin. All of the average recoveries were between 98% and 102%. Conclusion: The method is accurate
reliable and reproducible and can be used for the quality control of Jinggu tablet.
