摘要: 研究超声波辅助提取甘松中总黄酮的最佳提取工艺条件。在单因素试验基础上,选取乙醇体积分数、提取时间、液料比和提取次数进行Box-Behnken中心组合设计,以总黄酮提取率为响应值,采用响应曲面法优化提取工艺。结果最佳提取条件为:乙醇体积分数55%,提取时间35 min,料液比1:35(g/mL),提取3 次,该条件下总黄酮提取率为39.102 mg/g,与模型预测值40.275 mg/g的误差为3.00%。响应曲面法可以优化甘松总黄酮的提取工艺,为甘松质量控制提供了科学依据。

Abstract: To optimize ultrasonic-assisted extraction process of total flavononids from Nardostachys chinensis Batal.On the basis of the single factor test,ethanol concentration, extraction time,ratio of material and liquid,and extraction times were selected for Box-Behnken central composite designing.With extraction yield of total flavononids as response value,the extracting process was optimized by the response surface method(RSM).The optimized extraction conditions were as follows:ethanol concentration was 55%,the extraction time was 35 min,the ratio of material and liquid was 1:35(g/mL),the extraction times was 3 times.The extraction yield of total flavononids was 39.102 mg/g and the relative error was 3.00% that compared with actual value.The RSM technology optimization for extracting total flavononids from N.chinensis Batal. was suitable.In addition,it can be used to assist the quality evaluation of N.chinensis Batal.

Key words: response surface method, Nardostachys chinensis Batal, total flavononids, ultrasonic extraction optimization
