摘 要：Effects of solvent types and extraction methods were investigated for effective recovery of fatty oils from Fructus Leonuri fruit.Among the five solvents tested,dichloromethane gave the highest recovery with Soxhlet extract ion (SE),and ethanol gave the highest recovery with microwave assisted extraction (MAE).In addition,the fatty oil content of the MAE extract was found to be only slightly lower than that of SE,but MAE was shown to permit comparable extract ion efficiency with 30 fold reduction in extraction time and 2 fold reduction in solvent consumption.
