蜡梅花不同开放状态的精油成分分析

Study on Fragrant Constituents of Chimonanthus praecox (L.) Link during Three Booming Stages

摘要:

采用水蒸汽蒸馏法提取蜡梅花精油，采用气相色谱-质谱联用技术（GC-MS）对精油成分进行分析，研究花蕾、初展、全展三种不同开放状态蜡梅花中精油化学成分变化规律。结果表明三种不同状态的蜡梅花精油主要成分基本相同，其中芳樟醇含量随着开放度的增大，含量发生显著变化，并在初展状态的达到峰值的11.72%，其他主要香气成分的含量变化不大。

Abstract:

The essential oils which extracted by hydro distillation method was studied by GC-MS and evaluation methods during Chimonanthus praecox (L.) Link booming. The number and the contents of fragrant components of essential oils were changed during aroma releasing.The components of fragrant contents of essential oils were identified by searching the standard NIST05 database during the following three stages (buds, early spread, spread),and the variation of fragrant contents was studied as well. Results showed that the main fragrant components of different booming stages(buds, early spread, spread and final flowers) was approximately the same, whereas the relative percentage of linool increased significantly from the buds from early spread, arrived at the maximum of 11.72%.
