摘要
采用乙醇提取法从菊芋中提取总黄酮,在单因素试验的基础上用正交试验进行工艺参数的优化。结果表明,最优提取条件为:提取温度80℃,70%乙醇,料液比1:20,提取时间40 min。
In this paper, the ethanol extraction of flavonoids from halianths tuber was studied. On the basis of single factor tests,the orthogonal test was used in the optimization of technological parameters. Results showed that the optimum conditions are as follows： temperature 80℃ ,ethanol concentration70% ,the ratio of solid to liquid 1：20 and extraction time 40min.
