摘要: 以丝兰粉末为原料,综合运用单因素和正交试验设计,研究乙醇体积分数、液固比、提取时间、微波功率对丝兰皂甙提取率的影响。结果表明:微波辅助提取法中影响丝兰皂甙提取率的4个因素依次为乙醇体积分数>提取时间>液固比>微波功率,此方法的最佳提取工艺条件为乙醇体积分数70%、液固比80:1(mL/g)、提取时间10×20s(提取10次,每次20s,时间间隔2min)、微波功率480W,此条件下的皂甙提取率为2.18%。与以往常用乙醇浸提法相比,微波提取法可缩短80%的时间,且提取率提高41.56%。

Abstract: :Single factor and orthogonal tests were conducted to evaluate the effects of ethanol concentration, extraction time, material-liquid ratio and microwave power on extraction rate of yucca saponins. The results showed that the factors affecting microwave-assisted extraction rate of yucca saponins were ethanol concentration, heating time, microwave power and material-liquid ratio in sequence. The optimal extraction conditions were ethanol concentration of 70%, material-to-liquid ratio of 1:80 (g/mL), extraction time of 10×20 s and microwave power of 480 W. Under the optimal extraction conditions, the extraction rate of yucca saponins was 2.18%. Compared with ethanol extraction protocol, microwave-assisted extraction can save 80% time, and greatly improve the extraction rate by 41.56%.

Key words: yucca saponins, microwave-assisted extraction, ethanol extraction, extraction rate
