| 摘 要： | 利用超声法辅助提取光皮木瓜渣中的多酚,考察了乙醇浓度、料液比、超声时间、提取温度等因素对提取量的影响。通过单因素试验和正交试验确定了光皮木瓜渣多酚提取的适宜工艺条件为:乙醇体积分数55%,料液比1∶17,超声时间40 min,提取温度60℃,在此优化条件下,光皮木瓜渣多酚提取量为9.73%;该类光皮木瓜渣多酚粗提液具有较强的抗氧化活性,是一类具有开发价值的天然抗氧化剂。

| Abstract: | The ultrasonic extraction conditions of polyphenols from Chaenomeles sinesis are studied.The factors in fluencing extraction rate of polyphenols are investigated by single factor and orthogonal tests.The optimum extraction conditions are as follows:ethanol concentration 55%,solid-liquid ratio 1∶17,extraction time 40 min,and extraction temperature 40 ℃.Under these conditions,the extraction ratio of polyphenolic is 9.73%,Such polyphenol from Chaenomeles sinensis has strong antioxidant activity,would be hopefully for a new kind of natu ral antioxidant. |
