摘要: 为优化西洋参须根中人参皂苷类成分的提取工艺,采用西洋参须根为原料,通过酶-水法连续提取人参皂苷类成分,以总皂苷提取率为评判指标,通过响应面试验对提取工艺进行优化。结果表明酶法提取最佳工艺条件为:采用α-淀粉酶,加酶量7.3%、液料比30 mL/g、酶解时间1.2 h。酶解后继续采用水提法二次提取,水提法最佳工艺条件为:液料比27 mL/g、提取温度89 ℃、提取时间1.3 h。此条件下西洋参须根中总皂苷的提取率为16.61%。该方法提取率稳定、简便高效,提取率得到了显著提升,避免了资源浪费,为西洋参须根中人参总皂苷提取工艺方面填补了部分空白,也为下一步总皂苷纯化精制及活性探究提供参考与借鉴。

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
