Abstract: To optimize the simultaneous determination method of naringin and hesperidin, we compared the content difference of naringin and hesperidin of pomelo peel from different sources. Naringin and hesperidin content were determined by RP-HPLC on Luna C18 (2) column (4.60 mm×150 mm, 5 μm, 100 ?) at 30℃. The mobile phase was pure water-acetonitrile (81:19), adjusted to pH value of 2.4 with phosphoric acid. The UV detection wavelength was set at 283 nm. The flow rate was 1.0 mL/min. The calibration range of naringin and hesperidin was 0.0247- 0.989 μg (r=0.9999) and 0.0282- 1.130 μg (r=0.9999), respectively. The average recoveries of 3 levels of naringin and hesperidin were 91.46% and 92.66%, corresponding RSD were 1.81% and 1.22%. Through this method, the difference of naringin content of pomelo peel from different sources reached extremely significant level. But hesperidin was not detected. This method is simple and accurate, and can simultaneously determine naringin and hesperidin content in pomelo peel.
