采用毛细柱 GC-MS 和弹性石英毛细柱 GC Kovats 指数的鉴定方法,从月桂(Laurusnobilis L.)叶精油中鉴定出45个化合物,其中1,4-桉叶油素、水合桧烯等19个系该种植物中首次报道。系统地研究了月桂干叶与鲜叶、不同产地、当年生与多年生成分,首次报道月桂叶精油成分逐月动态变化,表明其得率和主成分1,8-桉叶油素含量均以7月最高。 Based on the identification of capillary column GC-MS and GC Kovats index, 45 compounds were identified from the essential oil of Laurus nobilis L., of which 19 were 1,4-eucalyptin and hydrated terpenes. Department of the plant was first reported. A systematic study was made of the dry leaves and fresh leaves of laurel, different production areas, current year, and multi-year production points. The monthly changes of the essential oil composition of laurel leaf were reported for the first time, indicating that the yield and the content of main components 1,8- eucalyptol were all 7 The highest month.
