摘要
为优化苦荞麦黄酮的回流提取工艺,采用单因素和响应面试验研究回流法,研究乙醇体积分数、液料比、提取温度、提取时间对苦荞麦中黄酮提取效果的影响。研究表明,最佳提取工艺条件为液料比6 mL/g,提取时间30 min,提取温度40℃,乙醇体积分数56%。在此条件下,苦荞麦中黄酮得率为3.378 mg/g,验证值为3.434 mg/g,误差为1.66%。
To obtain the optimum infusion extraction technology of flavonoids from buckwheat, the single-factor tests and response surface analysis are employed, including liquid/solid ratios, extraction temperature, infusion processing time and concentration of alcohol. The results indicate that the optimal extraction conditions are liquid/solid ratio 6 mL/g, infusion processing time 30 min, 56% alcohol and extraction temperature 40 ℃, respectively. Under these conditions, the predictive maximum yield of flavonoids from buckwheat is 3.378 mg/g, the validation value is 3.434 mg/g. The relative error between them is 1.66%.
