摘要

摘要: 本研究以薏米为原料,在单因素实验的基础上应用响应面法对其结合型多酚提取条件进行优化。以NaOH的消化浓度、消化时间以及乙酸乙酯浸提温度为单因素,以结合型多酚提取得率为指标,研究各因素交互作用对薏米结合型多酚提取得率的影响。实验结果显示该方法提取的最佳条件为NaOH浓度为3.26 mol/L,消化时间为4.6 h,浸提温度为53℃。此条件下得到结合型多酚的提取得率为(30.16±1.08)mgGAE/100 g,与模型预测值29.3237 mgGAE/100 g相近,说明该方法得到的薏米结合型多酚提取条件真实可靠,并具有较高的提取得率。

Abstract: In this study,adlay seed was used as the raw materials,and based on the single factor experiments,the response surface method(RSM)was employed to optimize the extraction conditions of bond polyphenols. The degrading concentrations of NaOH,time,and extracting temperature on ethyl acetate extraction were taken as single factors,and combined with bond polyphenols extraction rate as index,to research the influence between the interaction of various factors and the extraction rate of bond polyphenols in adlay. The results showed that the optimum conditions for extraction NaOH concentration was 3.26 mol/L,the degradation time was 4.6 h,and the extraction temperature of ethyl acetate was 53℃. Under this condition,the bond polyphenols extraction rate was(30.16±1.08)mgGAE/100 g,similar to the model predicted value 29.3237 mgGAE/100 g. It showed that the method of bound polyphenol extraction condition of coix seed was reliable,and had a high extraction efficiency.
