中文摘要: 以烟草废弃烟叶作材料,根据 Box-Behnken 中心组合试验设计原理,选取提取温度、超声时间、乙醇体积分数 作为优化因素,在单因素试验的基础上,采用响应面法对废弃烟叶中芦丁的提取工艺进行优化。试验结果表明芦丁提取 的最佳工艺参数为:提取温度 57.5 ℃、超声时间 20.3 min 和乙醇体积分数 32.6 %,提取率为 13.7 mg/g,与理论预测值的 相对误差为 1.0 %,说明响应面法可以很好地优化废弃烟叶中芦丁的提取工艺。这一结果可为烟草废弃物的综合利用提 供参考。
Abstract:Based on single factor experiments for extraction temperature, ultrasonic time and volume ratio of ethanol, the optimum extraction techniques of rutin from waste leaves was performed through the analysis of re- sponse surface method(RSM) which was designed by Box-Behnken Design(BBD). The experimental results showed that the optimum extraction parameters were as follows: extraction temperature at 57.5 ℃, ultrasonic time for 20.3 min and 32.6 % of ethanol volume ratio. The average extraction yield of rutin was 13.7 mg/g with
1.0 % of the relative error comparing with the theoretical value, demonstrating that response surface method could effectively optimize the extraction process of rutin from waste tobacco leaves. This result could provide ref- erences for the comprehensive utilization of tobacco waste.
