| 摘 要： | 采用响应曲面法的Box-Behnken模式，以盐酸和80%乙醇混合溶液作为提取液浸提棉子饼粕中棉酚工艺条件进行了研究，并建立提取棉酚的二次多项数学模型，探讨了主要因素的影响效应及其交互作用。采用响应曲面法优化得出的最佳工艺条件为：浸提温度60℃，提取液用量为26 mL·g-1，盐酸浓度为1 mol·L-1，浸提时间为3.6 h，提取次数1次时，提取量为8.80 mg·g-1。

| Abstract: | Optimizing extraction technology of gossypol from cottonseed meals with the hydrochloric acid and 80% ethanol mixed solution by Response Surface Methodology's Box-Behnken mode was studied. A quadratic equations model for gossypol extraction was built and effect of main factors and their corresponding relationships were obtained. The optimal extraction conditions of gossypol from cottonseed meals as follows: extraction temperature 60℃, volume of extractant 26 mL·g-1,hydrochloric acid's concentration 1 mol·L-1, extraction time 3.6 h,extracting times was 1, the yield of gossypol from cottonseed meals by hydrochloric acid and 80% ethanol mixed solution was 8.80 mg·g-1. |
