中文摘要：本文采用气相色谱-质谱联用(GC-MS)仪研究了互叶白千层枝条的成熟度、热风干燥及物料状态对其精油化学组分的影响。结果表明:从互叶白千层嫩叶提取的精油中烯醇类物质的含量比老叶中的含量高,烯类物质含量比老叶中低;热风干燥导致精油中松油烯-4-醇含量降低,1,8-桉叶素含量增加,其它组分没有明显变化规律;物料发酵后,烯醇类物质含量降低,烯类物质及1,8-桉叶素含量增加。因此,互叶白千层加工过程中,为了获得高品质的精油,需要根据枝条的生长情况把握好收割时间,同时收割好物料及时进行加工,避免堆积引起发酵,在生产能力较小的时候,可以适当将物料进行干燥处理,延长加工时间,缓解生产压力。

外文摘要：The influences of the branches maturity,the hot air drying and material status on the chemical compositions of Melaleuca ahemifolia oil were studied by GC-MS.The results showed that the contents of olefinic alcohol in essential oil extracted from immature leaves of Melaleuca ahemifolia was higher than that in old leaves,and the contents of alkene was lower than that in old leaves.After the material was dried by hot air,the contents of terpineol-4-ol in essential was reduced,the contents of 1,8-cineole was increased,and the other components had no obvious changes.After the material fermentation,the contents of enols decreased,the content of alkenes and 1,8-eucalyptol increased.Therefore,in order to obtain high-quality essential oil in the progress of processing leaves of Melaleuca alternifolia,it was necessary to grasp the harvest time according to the growth condition of branches.At the same time,the harvested materials were processed in time to avoid accumulation and fermentation.When the production capacity was small,the materials could be properly dried to prolong the processing time and relieve the production pressure.
