摘要:

为了优化滁菊中黄酮类化合物的提取工艺条件,在60℃条件下,采用水和不同体积分数的乙醇溶液作溶剂,提取滁菊中的黄酮类化合物,结果表明乙醇提取明显优于水提。在此基础上,采用正交试验设计,对提取过程中乙醇体积分数、温度、固液比3 个影响因素进行研究,结果表明:利用乙醇溶液作为溶剂,提取滁菊黄酮的最佳条件为乙醇溶液体积分数80%、提取温度70℃、固液比1:100(g/mL),在此条件下,提取黄酮类化合物平均得率为75.46mg/g。3 个因素中,固液比对黄酮类化合物提取的影响最大。

Abstract:

Pure water and aqueous solutions of ethanol at different concentrations were used to extract total flavonoids from the flowers of Dendranthema morifolium (Ramat) Tzvel. cv. Chuju at 60 ℃, respectively, and ethanol aqueous solution was the selected solvent for total flavonoids extraction based on experimental results. This was followed by the optimization of the process for total flavonoids extraction using orthogonal array design. The results indicated that the optimum extraction conditions were determined as follows: ethanol concentration 80%, extraction temperature 70 ℃ and solid-to-liquid ratio 1:100. Among these conditions, solid-to-liquid ratio exhibited the most significant effect on total flavonoids extraction.

Key words: Dendranthema morifolium (Ramat) Tzvel. cv. Chuju, total flavonoids, orthogonal array design, extraction
