响应面法提取烟叶有效物质工艺优化

摘要

采用溶剂法提取烟叶中有效物质，应用响应面法考察了提取时间、提取温度及提取物料比3个因素对提取效率的影响。得出最适宜提取工艺参数为：提取温度，42.54℃；提取时间，6.0 h；提取物料比12.31 mL/g。在此最适宜提取条件下可得到提取率为7.94%，其中烟碱质量分数32.25%，蒎烷质量分数23.14%，天然维生素E质量分数14.11%。

Abstract：

The extraction of active ingredients from discard tobacco leaves was investigated by solvent extraction. The effect of extraction time, extraction temperature and liquid-solid ratio was studied using the Response Surface Method (RSM) with the Box-Behnken Design (BBD) method. The optimized extraction temperature was 42.54 ℃, extraction time was 6 hours and liquid-solid ratio was 12.31 mL/g. The extraction yield of essential oil was achieved as high as 7.94% under above conditions and nicotine accounted for 32.25%, pinane for 23.14% and vitamin E for 14.11% of the oleoresin.

Keywords： active ingredients； Vitamin E； solvent extraction； response surface methodology
