摘要: 为了探讨藜麦(Chenopodium quinoa Willd.)种子黄酮的乙醇提取最佳条件,进而为藜麦黄酮的开发和高黄酮品种的筛选提供理论依据,采用4因素3水平正交试验设计,探讨了乙醇体积分数、料液比、提取时间和提取温度对藜麦种子黄酮含量的影响。结果表明,各因素对藜麦种子黄酮提取含量的影响程度为乙醇体积分数>提取温度>料液比>提取时间。藜麦种子黄酮最佳提取条件为乙醇体积分数90%、料液比1∶50(g∶mL)、提取时间50 min和提取温度50 ℃。

Abstract: In order to optimize the extraction process of flavonoids from Chenopodium quinoa Willd. seeds, as well as to provide theoretical basis for flavonoids exploitation and high flavonoids variety screening. Orthogonal design L9(34) test including four factors such as ethanol volume fraction, solid-liquidratio, extracting time and extracting temperature was investigated. The results showed that the influence degree of each factor on extraction content of flavonoid from Chenopodium quinoa Willd. seeds were ethanol volume fraction> extraction temperature> solid-liquidratio> extraction time. The optimum extracting conditions were extracting reagent 90% of ethanol, 1∶50(g∶mL) of solid-liquidratio, 50 min of extraction time and 50 ℃ of extraction temperature.
