Abstract: Purpose: A solid-phase extraction procedure for the separation and purification of naringin (NG) was developed using strong anion exchange (SAX) cartridge. Method: Naringin was adsorbed onto the cartridge by electrostatic interaction between naringin and functional groups. Several variables affecting the elution performance of SAX, such as ionic strength of elution, elution volume and elution rate, were studied. Results: The application of 5 mL of sodium bicarbonate solution (0.1 mol/L, pH = 9.0) to elute SAX cartridge at a flow rate of 0.5 mL/min resulted in a recovery rate of 91%. Conclusions: The established method is simple and efficient.

Key words: solid phase extraction, strong anion exchange (SAX), naringin
