摘要: 为优化小叶金露梅叶中总黄酮的提取工艺,在单因素实验的基础上,选取乙醇浓度、料液比、提取温度为自变量,以总黄酮提取得率和抗氧化能力为响应值,进行Box-Behnken中心组合实验设计,采用响应面法(RSM)评估以上因素对总黄酮提取得率及抗氧化能力的影响。结果表明,小叶金露梅叶总黄酮提取的最佳工艺为乙醇浓度51%,料液比30∶1(mL/g),提取温度80 ℃,在此条件下总黄酮提取得率为2.83%,对DPPH的清除率为16.37%。响应面优化得到的提取工艺合理可靠,可用于小叶金露梅叶总黄酮提取过程的优化控制。

Abstract: In order to optimize the extraction yield of total flavonoids in Potentilla parvifolia leaves,the optimal extraction process was determined.Based on the single factor experiment,ethanol concentration,material-liquid yield and extraction temperature were selected as independent variables,and the total flavonoid extraction yield and antioxidant capacity were used as the response values.The Box-Behnken center combined experimental design was carried out,and the response surface methodology (RSM) was used to evaluate the effects of the above factors on the extraction yield and antioxidant capacity of total flavonoids.The results showed that the optimum extraction conditions of total flavonoids were ethanol concentration of 51%,material-liquid yield of 30∶1 (mL/g),extraction temperature of 80 ℃.Under these conditions,the total flavonoids extraction yield was 2.83%,the anti-oxidant capacity was 16.37%.The extraction process optimized by RSM was reasonable and reliable.And it could be used for optimal control of flavonoid extraction process in leaves of Potentilla parvifolia.
