Optimization of extraction technology of ginsenosides from ginseng leaves by response surface method
摘要
Abstract
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.关键词
