Title: Study on the Ultrasonic-Associated Alkali Extraction of Hesperidin from Citrus Aurantium
Abstract: To study on the ultrasonic-associated alkali extraction of hesperidin from Citrus aurantium by singlefactor and orthogonal test.Hesperidin was extracted with ethanol-NaOH and determined by UV-visible spectrophotometry.The optimal ultrasound-associated extraction conditions were 4 times the mass of 65 % ethanol-NaOH(pH=13) at 50 ℃ for 50 minitus and extracting 3 times,the extract was precipitated for 10 hours at pH=7.The content of hesperidin was 32.3 mg/g.The optimal extraction technology was stable and feasible.
