摘要:

以葛花为原料,正丁醇- 水两相系统为溶剂提取葛花总异黄酮。在单因素试验基础上,利用Box-Behnken中心组合试验和响应面分析法,对葛花总异黄酮提取工艺参数进行优化。结果表明:提取时间1.30h、提取温度70℃、正丁醇- 水的配比1:1(V/V)、液固比55:1(mL/g)时,葛花总异黄酮的实际提取率为96.24%,预测值为97.50%,实验值与预测值相符,样品纯度可达73.89%。采用响应曲面法对葛花异黄酮提取条件进行优化合理可行。

Abstract:

Flos puerariae was used as raw material to extract isoflavone using n-buatnol/water two-phase system as solvents. Based on single factor experiments, the optimal extraction processing was explored by central design composite experiments combined with response surface methodology. Results showed that the optimal extraction processing parameters were extraction time of 1.3 h, extraction temperature of 70 ℃, n-buatnol-water ratio of 1:1 (V/V) and material-liquid ratio of 1:55 (g/mL). Under these optimal conditions, the extraction rate of isoflavone was 96.24%, which was very close to predicted value. Therefore, it is feasible to optimize the extraction processing of isoflavone from Flos puerariae by response surface methodology.

Key words: two-phase system, Flos puerariae, isoflavone, response surface methodology, extraction
