海南桃金娘叶挥发油化学成分GC-MS分析

目的： 分析鉴定海南桃金娘叶的挥发油化学成分。 方法： 采用水蒸气蒸馏法提取海南桃金娘叶的挥发油，并用气相色谱-质谱联用技术对其化学成分及其含量进行分析。 结果： 从海南桃金娘叶的挥发油中共鉴定出50种化合物，占挥发油总量的99.98%，且以萜类为主，其中主要成分有石竹烯（13.96%），石竹烯氧化物（13.15%），2，4，5三甲基苯甲醛（9.15%），2-十二烯醛醇（8.55%），1，1，4，8-四甲基-4，7，10-环十一三烯（5.05%），反式-1，4-二甲基-β-亚甲基-环己醇（4.22%）。 结论： 海南桃金娘叶挥发油具有良好的应用价值，该研究为其药用功能提供了理论基础，及其综合开发利用提供了一定的理论依据。

Chemical Constituent of Volatile Oil in Folium Rhodomytrti Tomentosae from Hainan Province with GC-MS Analysis

Objective: Analyzing and identifying the constituents of the chemical constituent the Folium Rhodomyrti Tomentosae. Method: The essential oils were extracted by steam distillation, and then the constituents were separated and identified by GC-MS. Result: 50 compounds from the volatile oil were identified, which account for 99.98 % of total volatile oils, and of them the main components are terpenes The main constituents are caryophylleneoxide(13.15%),benzaldehyde,2,4,5-trimethyl-(9.15%),2-dodecenal(8.55%),4,7,10-cycloundecatriene,1,1,4,8-tetramethyl-,cis,cis,cis(5.05%),cyclohexaneethanol,4-methyl-.beta.-methylene-,trans-(4.22%). The content (13.96%) of caryophyllene is the highest. Conclusion: The essential oil from Folium Rhodomyrti Tomentosae showed high application value,and this study provided a chemical basis as a medicinal herb, and theoretical basis for the comprehensive utilization of the essential oil from leaf of Folium Rhodomyrti Tomentosae.
