To determine the content of hesperidin and naringin in the hull of citrus reticulata Blnco,citrus simenis(L.)Osbeck and citrus grandis(L.)Osbeck by the way of HPLC.With shimadzu vp-ODS(4.6 mm×150 mm,5 μm) colum and the mobile phase is CH3CN-(H3PO4.pH=3.5)(22︰78),the velocity of flow is 1.20mL.min-1and the detective wavelength is favourable 283 nm.The separate degree between the determination component and other components is favourable(R>1.5),the linearity rang of hesperidin and naringin are 0.022μg^1.80 μg and 0.023μg^1.90 μg respectively,The average recoveries of hesperidin and naringin are 99.3%,97.6% respectively and their RSD are 1.4%,2.3% respectively.Conclusion:This method is convenient and easy,its result can be used to afford the feasibility to confirm material of the two active components.
