| 摘 要： | 研究茜草总黄酮的提取工艺条件。采用热浸提法提取茜草总黄酮,硝酸铝显色法测定总黄酮提取率。通过单因素试验研究乙醇体积分数、料液比、提取温度、提取时间对黄酮提取率的影响,通过正交试验进一步优化提取工艺条件。单因素试验结果显示,乙醇体积分数50%、提取温度70℃、提取时间2.5h、料液比1:40(g/mL)条件下茜草总黄酮提取率较高;正交试验结果表明:茜草总黄酮的最佳提取工艺为60%、乙醇溶液提取2h、提取温度70℃、料液比1:40(g/mL),此条件下茜草总黄酮提取率为1.67%。本工艺简单可行,有较好的参考价值。

| Abstract: | This study was carried out to optimize the hot water extraction of total flavonoids from madder root.The effects of 4 process parameters including ethanol concentration,material-to-liquid ratio,temperature and extraction duration on extraction efficiencywere investigated by one-factor-at-a-time method and orthogonal array design.The results form the one-factor-at-a-time experiments showed that the optimal extraction conditions were 50% aqueous ethanol as extraction solvent at a material-to-liquid ratio of 1... |
