Abstract:

To optimize the extraction process for ginsenosides from the fibrous roots of American ginseng,the enzyme-water method was used for continuous extraction of ginsenosides from American ginseng. The total ginsenosides extraction yield was used as the evaluation index,and the extraction process was optimized using the response surface methodology. The results showed that the optimal enzymatic extraction conditions were as follows: α-amylase with an enzyme concentration of 7.3%,a liquid/solid ratio of 30 mL/g,and an enzymatic hydrolysis time of 1.2 h. After enzymatic hydrolysis,a secondary water extraction was performed,and the optimal conditions were as follows: a liquid/solid ratio of 27 mL/g,an extraction temperature of 89 ℃,and an extraction time of 1.3 h. Under these conditions,the total ginsenosides extraction yield reached 16.61%. Since it is stable,simple,and efficient,this method has significantly improved the extraction yield and avoided the waste of resources. It partially fills a gap in the extraction process of total ginsenosides from the fibrous roots of American ginseng and provides a reference for further purification,refinement,and activity studies of total ginsenosides.

Key words: American ginseng, fibrous roots, ginsenosides, extraction process, response surface methodology, single factor experiment, ultraviolet spectrophotometry
