Abstract

The ginseng root was used as the experimental material to study the extraction process of ginseng root saponins by enzyme-assisted ultrasonic method, and the optimum process conditions were obtained. The ginsenoside Re was used as the standard. The total ginseng root saponins were extracted by enzyme-assisted ultrasonic method. The optimal extraction process was determined by orthogonal test with the percentage of total ginseng root saponins as indicators. The optimal combination of enzyme-assisted ultrasonic extraction of total ginsenosides was determined to be A2B2C3: pH6.0, enzymatic hydrolysis temperature 35℃, and solid-liquid ratio 1:20. The extraction rate of total ginsenosides from ginseng roots can be improved by enzyme-assisted ultrasonic method.
