摘  要:
测定了木槿花醇溶性色素在可见光区的最大吸收波长;在单因素试验的基础上,采用正交试验,以吸光度与浸提液总体积之积为指标,对提取温度、浸提时间、超声时间和料液比进行优选研究,采用邻苯三酚自氧化法考察该色素清除超氧自由基活性。结果显示最佳提取工艺条件为提取温度40℃,料液比1∶50(W/V,g∶mL),浸提时间1 h(包括超声时间45 min);该色素具有一定的清除超氧自由基活性。

摘  要:
The maximum absorption wavelength of the red pigment from Hibiscus syriacus L.was mensurated.On the basis of single factor tests,orthogonal design was carried out to find the optimum extracting technology by detecting the product of the absorbance and the solvent volume(A·V),among extracting temperature,soaking time,ultrasonic time and material-solvent ratio.The pyrogallol autoxidation method was used to evaluate the capability to scavenge superoxide radicals of the red pigment.The results indicated that the optimum technology was extracting temperature 40 ℃,material-solvent ratio 1∶50(W/V,g∶mL),soaking time 1h(including ultrasonic time 45 min),and the red pigment has the capability to scavenge superoxide radicals.
