摘要
为优化人参叶总皂苷提取工艺,采用单因素试验,考察温度、时间、液料比对人参叶中总皂苷得率的影响。再采用3因素3水平的响应面分析法确定人参叶总皂苷提取的优化工艺,同时建立人参叶总皂苷提取的二次项数学模型,并验证其可靠性。结果表明:热水浸提法提取人参叶总皂苷的最佳条件为温度100℃、时间4.2 h、液料比16。在最佳条件下,人参叶总皂苷得率为人参叶质量的14.23%。
In order to optimize the extraction process of total ginsenosides from ginseng leaves, firstly we utilized one-factor experiment to investigate the influences of the factors （ temperature, treatment time, and liquid -material ratio） on the extraction yield of total ginsenosides. Then we determined the optimal extraction process by the response surface methodology with 3 factors and 3 levels, and established the quadratic mathematical model for the ginsenosides extraction, and finally verified its reliability. The optimal extraction conditions for the hot water extraction of total ginsenosides were as follows：temperature 100 ℃, treatment time 4. 2 h, liquid-material ratio 16. Under this condition, the yield of total ginsenosides from ginseng leaves was 14. 23% of ginseng leaves’ mass.
