摘要:

目的 探究暴马丁香花挥发油中组分，揭示其研究和利用价值，以便更好的保护和利用长白山暴马丁香资源。方法 用CO₂超临界萃取方法提取暴马丁香花挥发油，用GC-MS对挥发油中组分进行定性并用面积归一化法确定各组分及相对含量。结果 用GC-MS可分离出45个组分，占总含量97.84%，定性鉴定了其中39种组分。含量较高的成分有环庚三烯(17.16%)、2-(苯基甲氧基)丙酸甲酯(17.27%)、2R-4-(4-羟基苯基)-2-丁醇(11.74%)和苯乙醇(6.86%)。结论 用超临界CO2流体萃取暴马丁香挥发油成分并用GC-MS对其成分进行检测，方法快速，高效并且可避免溶剂残留，为暴马丁香开发提供理论依据。

Abstract:

OBJECTIVE To explore the components of volatile oil from flowers of Syringa reticulate, and reveal its use and research value to make better protection and utilization of Syringa reticulata resources on Changbai Mountain. METHODS The volatile oil of Syringa reticulata was extracted by supercritical CO₂ extraction technology, and the components of the oil were qualitatively by GC-MS and relative content of each component was determined by area normalization method. Results The 45 chemical components were separated by GC-MS, which were 97.84% of the total oil, and 39 compounds of them were also identified. The main ingredients were: 1,3,5-cycloheptatriene(17.16%), 2-(phenylmethoxy)-, methyl ester (17.27%), benzenepropanol, 4-hydroxy-.alpha.-methyl-, (R)- (11.74%), phenylethyl alcohol (6.86%). CONCLUSION This method，using supercritical CO2 extraction Syringa reticulate volatile oil and analysis by GC-MS, is characterized by efficient and rapid as well as avoiding residual solvent. The experiment provides a theoretic basis for Syringa reticulate exploitation.
