Abstract:
The present study established an RP-HPLC method for simultaneous determination of two active components in Qingfei Paidu Granules and investigated the transfer rates of neohesperidin and naringin in the preparation process to provide references for improving the quality control standard and production of Qingfei Paidu Granules.RP-HPLC was performed on a YMC Triart C_(18) column(4.6 mm×150 mm, 5 μm)with column temperature of 30 ℃, acetonitrile(A) and 0.2% phosphoric acid solution(B) as mobile phases for gradient elution at a flow rate of 1.0 mL·min~(-1) and detection wavelength of 284 nm.Good linearity was observed for naringin at 0.10-1.0 μg(R~2=0.999 9) and neohesperidin at 0.12-1.2 μg(R~2=0.999 9).The average recovery of naringin was 99.52% with an RSD of 1.2%, and that of neohesperidin was 100.8% with an RSD of 1.2%.The transfer rates of naringin and neohesperidin between medicinal materials, extracts, concentrates, and granules were measured by this method.The average transfer rate of naringin from medicinal materials to granules was 54.89%±4.38%, and that of neohesperidin was 57.63%±5.88%.The process from medicinal materials to extracts was presumedly the key link affecting the whole preparation process.The established method is simple and sensitive and can be adopted for the quality control of Qingfei Paidu Granules.Meanwhile, it can be used to investigate the transfer rate of neohesperidin and naringin in the preparation of Qingfei Paidu Granules, and further improve the quality control standard of Aurantii Fructus Immaturus in Qingfei Paidu Granules.
