摘　　要：目的:分别对广西忻城产红腺忍冬新鲜叶片及干燥叶片水蒸气蒸馏法所得提取物的化学成分进行分析比较。方法:采用GC-MS联用仪对红腺忍冬叶水蒸气蒸馏法所得提取物化学成分进行鉴定。结果:在鲜叶挥发油中共分离得到93个组分,鉴定了其中的39个,占新鲜叶片全油的83.62%;在干叶挥发油中共分离得到88个组分,鉴定了其中的51个,占干燥叶片全油的72.09%,共有组分为17个。红腺忍冬新鲜叶片的主要成分为棕榈酸、叶绿醇和亚麻酸甲酯,相对百分含量分别为11.90%、11.79%和7.08%,而红腺忍冬干燥叶片的主要成分为芳樟醇、叶绿醇和反式角鲨烯,相对百分含量为27.62%、7.57%和4.70%.结论:干燥前后红腺忍冬叶挥发油的种类及含量有明显差异。Objective：To compare volatile oil of Lonicera confusa（red gland Lonicera） fresh leaves with dry leaves and provide evidence for further study of Lonicera confusa leaves.Methods：GC-MS was used to identify chemical composition in volatile oil in red gland Lonicera leaves.Results：93 chemical components were separated in fresh leaves in which 39 chemical components were identified;88 chemical components were separated in dry leaves in which 51 chemical components were identified. The main components of fresh leaves of red gland Lonicera were n-Hexadecanoic acid（11.90%）,Phytol（11.79） and 9,12,15-Octadecatrienoic acid,methyl ester,（Z,Z,Z）（7.08）;The main components of dry leaves of red gland Lonicera were 1,6-Octadien-3-ol,3,7-dimethyl-（27.62%）,Phytol（7.57%） and 2,6,10,14,18,22-Tetracosahexaene,2,6,10,15,19,23-hexamethyl-,（all-E）（4.70%）.Conclusion： There are significant differences between volatile oil between fresh and dry leaves.
