摘　　要：采用少溶剂微波蒸馏同时萃取法从神农香菊鲜叶获得精油,实验考察了萃取剂种类和用量、微波辐照时间以及微波辐照功率对精油得率的影响,得到的最佳操作条件为液料比2∶1 mL·g^(–1),微波辐照时间40 min,微波辐照功率540 W。气质联用法分析了精油的化学成分,主要成分依次为乙酸桃金娘烯酯(21.72%)和顺式香桧醇(19.23%)。In this study,solvent-less microwave distillation and simultaneous extraction approach was used for obtaining of essential oil from leaves of Dendranthenma indicum var.aromaticum.Effects of extractant type and dosage,microwave irradiation time and microwave irradiation power on the yield of essential oil were investigated.The optimum operating conditions were as follows:the liquid-solid ratio was 2∶1 mL·g^(–1),microwave irradiation time was 40 min,and microwave irradiation power was 540 W.The chemical composition of the essential oil was analyzed by gas chromatography-mass spectrometry,and the main components were myrtenyl acetate(21.72%)and cis-sabinol(19.23%).
