摘要: 冰菜是近几年引入到我国的一种新型高价值保健蔬菜,日益受到大众喜爱。本研究以冰菜为研究对象,采用超声辅助提取法提取总黄酮,以总黄酮提取率为评价指标,在单因素试验结果的基础上,利用正交法对提取工艺条件进行优化,考察冰菜总黄酮提取物对1,1-二苯基-2-三硝基苯肼(DPPH)和羟基自由基的清除能力。结果表明:在乙醇体积分数为60%、料液比为1∶15、提取温度为50 ℃、提取时间为120 min的条件下,冰菜总黄酮提取率可达4.91%。在质量浓度为0.02~0.10 mg/mL范围内,冰菜总黄酮提取物均具有抗氧化活性,且质量浓度越大,抗氧化能力越高。

Abstract: Mesembryanthemum crystallinum is a new type of high-value health vegetable introduced into China in recent years, which is increasingly popular in the public. In this study, the M. crystallinum was used as the material to extract total flavonoids by ultrasonic-assisted extraction. Taking the extraction rate of total flavonoids as the evaluation index, on the basis of single-factor test results, the orthogonal extraction method was used to optimize the extraction process conditions, and the scavenging ability of total flavonoids from the M. crystallinum to 1,1-diphenyl-2-picrylhydrazyl(DPPH)and superoxide anion free radical was estimated. The results showed that the extraction rate of the total flavonoids reached 4.91% under the conditions of ethanol concentration of 60%, material-liquid ratio of 1∶15, extraction temperature of 50 ℃ and extraction time of 120 minutes. Within the concentration range of 0.02-0.10 mg/mL, the total flavonoids extract of M. crystallinum had antioxidant activity, and the higher the concentration of the extract, the higher the antioxidant capacity.

Key words: Mesembryanthemum crystallinum, total flavonoids, orthogonal design, antioxidant activity
