摘要
利用分光光度法对酸果蔓提取物的抗氧化活性进行了检测,并研究了在不同条件下提取物的稳定性。结果表明,酸果蔓提取物对羟自由基、超氧阴离子自由基的清除率分别是78.4%、91.5%,对脂质过氧化的抑制率为85.7%。在酸性及氯化钠溶液中能稳定存在,有较好的光稳定性,在75℃下有较好的热稳定性。
The antioxidative activity of cranberry extracts and its stability in different conditions were studied with photometric method. The results showed: The scavenging percentage of cranberry extracts to hydroxyl radical is 78.4%, and to superoxide radical is 91.5%, while the extracts inhibitory effect on lipid peroxidantion is 85.7%. It is very stable in acid solution, NaC1 solution and under 75"(2. The effect of light on stability is very little.
