Solvent-thermal Extraction Technology of Naringin from Gongshui White Pomelo Peel
Abstract：Solvent-thermal method was applied for extracting naringin from middle shaddock peel of Enshi Gongshui by using ethanol-water mixture as the solvent.The naringin was determined by ultraviolet spectrophotometry,and the orthogonal experiment was used in the optimization of technological parameters in this study at the same time.The results showed that the best process conditions were as follows： ethanol volume fraction was 70%,shaddock peel powder size was 120 mesh,filling factor was 80%,extraction temperature was 60℃ and extraction time was 3h.The naringin extraction ratio reached 8.76 by the optimum conditions.
