Abstract

Microwave-assisted extraction (MAE) was compared with room temperature extraction (RTE) and reflux temperature extraction (RFX) on the extraction of ginsenosides from fresh American ginseng root. Extraction times of 5, 10, 30 and 60 min were investigated. An 86 - 300% increase in extraction rate was observed by raised temperature. The use of microwave energy instead of hotplate heating in the extraction resulted in a 31 - 96% increase in extraction rate with the exception of ginsenoside Re. Visual analysis of the chromatographs of extracts helps choose conditions for selectively obtaining specific ginsenosides enriched extracts.
