摘要
研究仙人掌水溶性粗多糖的提取工艺及抗氧化性能。采用单因素试验和L(933)正交试验设计,考察提取温度、时间、料液比等因素对提取率的影响,并采用水杨酸法考察仙人掌粗多糖抗氧化性能。结果表明:温度是影响粗多糖提取的重要因素。优化工艺条件为:提取温度80℃,提取时间1h,固液比为1:60。抗氧化试验表明仙人掌粗多糖有较好的抗氧化活性。
Study on the extraction technology and antioxidant activity of polysaccharides from Opuntia dillenii Haw. Single factor test and orthogonal test design methods L9 （3^3） were applied to analyze the influencing factors such as extraction temperature, extraction time and material-water ratio on the extraction of the polysaccharides. The salicylic acid method was used to inspect the ability to antioxidant activity of polysaecharides from Opuntia dillenii Haw. Results showed that temperature was an important fact or for the extraction rate of the polysaceharides. The optimum extraction conditions were as follows： extraction temperature 80 ℃,material-water ratio1：60 and extraction time 4 h.The experiment of antioxidant activity shows that Opuntia dillenii Haw polysaceharides has good antioxidant activity.
