Abstract: Objective:To optmize the actetone extraction processing for bitterness such as naringin,limonin and nornilin in Guanxi pomelo.Methods:Study the effects of different tissue materials to,degrease or not degrease with different degrease solvents for extraction rate,and to optimize the extraction conditions,including actetone dosage,extract time,temperature and pH by orthogonal test.Results:The optimum conditions for actetone bitterness extract are as follows 20 times actetone(V/m), extracting in water bath for 15h at 40℃and pHT.0. Conclusion:The new extraction method can extract the primary bitterness (naringin,limonin and nomilin)from Cuanxi pomelo.
