摘　　要：为探索蒸馏工艺对岗松(Baeckea frutescens)精油品质的影响,采用水中蒸馏、水上蒸馏、扩散蒸馏、复蒸蒸馏和同时萃取蒸馏5种蒸馏方式提取岗松枝叶精油,对精油得油率和成分进行分析。结果表明,复蒸蒸馏精油得油率最高。采用复蒸蒸馏获取岗松精油时,设置液料比8∶1,蒸馏2 h,得油率为1.101%;精油中,β-蒎烯、4-松油醇、1,8-桉叶素和芳樟醇含量均符合广西地方标准DB45/T 1064—2014对特征组分的要求。试验结果可为岗松精油工业化生产提供参考。In order to investigate effects of distillation methods on quality of Baeckea frutescens essential oil,five distillation methods were used to extract essential oils from B.frutescens leaves and branches,including distillation in water,distillation above water,diffusion distillation,re-distillation and simultaneous extraction distillation,yields and components of essential oils were analyzed.Results showed that yield of essential oil by redistillation was the highest.When using re-distillation to extract essential oil,yield was 1.101%based on material to water ratio of 8∶1 and distillation time of 2 h.In essential oil extracted by re-distillation,contents ofβ-pinene,4-terpineol,1,8-cineole and linalool met characteristic component requirements in Guangxi local standard DB45/T1064—2014.Results couldprovide references for industrial productions of B.frutescens essential oils.
