金银花叶挥发油的GC-MS分析

Study on Essential Oil from Leaf of Lonicera japonic by GC-MS

[目的]对金银花叶挥发油的化学成分进行分析,为金银花的综合利用提供指导。[方法]采集金银花叶,干燥,粉碎,采取水蒸气蒸馏法提取其挥发油,GC-MS分析其化学成分。[结果]在金银花叶挥发油中检测出29个化合物,确认26个化合物。这些化合物多为有机酸和有机酸酯。金银花叶挥发油与金银花挥发油有许多相同的化学成分。这些化合物可能是它们具有相似功能的物质基础。[结论]金银花叶挥发油具有潜在的应用价值。

[ Objective ] To analyze chemical constituents in the volatile oil from leaves of Lonicera japonic, provide instruction for comprehen- sive utilization of Lonicera japonic. [ Method ] The leaves of Lonicera japonic were collected and dried, their volatile oil were extracted by steam distillation method. Then the chemical constituents of volatile oil was analyzed by GC-MS. [ Resuh ] There are 29 compounds were detected, among which, 26 compounds were confirmed, which are mainly organic acid and organic acid esters. Some chemical consituents were found similarly in the leaves volatile oil and the flowers volatile oil. These compounds are the material foundation for similar functions. [ Conclusion] The leaves volatile oil of Lonicera japonic has the latent value of application.
