摘　　要：以芒果核为原料,对芒果多酚的提取纯化工艺进行了研究。结果表明,采用微波萃取法提取芒果多酚的最佳工艺条件为乙醇浓度60%,提取时间2.5min,料液比1:15(w/v),微波功率为385W。大孔吸附树脂纯化芒果多酚的最佳工艺参数是:以AB-8树脂为吸附树脂,以4mg/mL的多酚浓度,2BV/h的流速进行上样,采用60%的乙醇以0.5BV/h的流速洗脱,洗脱体积3BV。Polyphenol was extracted from mango kernel seeds by microwave-assisted extraction method and purified by the macroporous resin.The results showed that through single factor and orthogonal test,the best extracting conditions for microwave-assisted extraction method was：60% alcohol as extracting solvent with a solid/solvent ratio of 1：15（w/v） and microwave power of 385 W extracting for 2.5 min.The optimum adsorption and separation conditions for the crude extract on AB-8 macroporous adhesive resin column were as follows：the feed concentration of 4 mg/mL with flow rate of 2 BV/h,The desorption solvent was 3 BV of 60% ethanol with flow velocity of 2 BV/h.
