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 analyze and compare the chemical constituents of the extracts obtained from the steam distillation of fresh and dried leaves of Xincheng honeysuckle grown in Xincheng, Guangxi. Methods: The chemical constituents of the extract obtained from the steam distillation of Lonicerae Japonica leaves were identified by GC-MS. Results: Ninety-three components were identified in the volatile oil of fresh leaves, of which 39 were identified, accounting for 83.62% of the total oils in the fresh leaves; 88 components were isolated from the volatile oil of the dried leaves, of which 51 were identified, accounting for 72.09% of the total dry oil leaves, the total components of 17. The main components of the fresh leaves of Lonicera chrysantha were palmitic acid, phytol and linolenic acid methyl ester, the relative contents were 11.90%, 11.79% and 7.08%, respectively, while the main components of the dried leaves of Lonicera giganteum were linalool, Green alcohol and trans-squalene, the relative percentages were 27.62%, 7.57% and 4.70% .Conclusion: There are significant differences in the types and contents of the essential oil before and after dried Rhizoma.
