水红花子花旗松素乙醇回流法提取工艺优化

摘要

Alstraet:Researched the ethanol refluxing extraction process for taxifolin of fructus polygoni orientalis.The single-factor test based on the selected ethanol concentration,extraction time,solid-liquid ratio as independent variables,and the extraction yiele of taxifolin was the response value.The response surface methodology was used to optimize the extraction conditions,the results showed that:the optimum extraction conditions of taxifolin were ethanol concentration 63％,extracting time 3.4 h,solid-liquid ratio 1 ∶ 19(m ∶ V),extracting temperature 95 ℃,extraction times 2,the extraction yield of taxifolin is 7.2 mg/g.%研究水红花子花旗松素乙醇回流法提取工艺.在单因素试验的基础上,以乙醇浓度、提取时间、料液比为自变量,以花旗松素提取量为响应值,利用响应面法优化水红花子中花旗松素的提取条件.结果表明:花旗松素的最佳工艺条件为乙醇体积分数63％、提取时间3.4h、料液比1∶19(m∶V)、提取温度95℃、提取2次,该条件下,花旗松素提取量为7.2 mg/g.
