摘要：

The extractions of ginsenosides Rg(1) and Rb-1 from ginseng root under atmospheric pressure by focused microwave-assisted technique have been investigated. The parameters used for the optimization were solvent composition, extraction time, and applied microwave power. The ginsenosides were quantified by high-performance liquid chromatography equipped with UV/Vis detector. The results of the 15-min microwave-assisted extraction (0.28% of Rg(1) obtained in 70% water-ethanol and 1.31% of Rb-1 obtained in 30% water-ethanol under 150 W of microwave power) were better than that from 10-h conventional solvent extraction (0.22% of Rg(1) and 0.87% of Rb-1 obtained in 70% water-ethanol).
