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2h,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.
Abstract
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 dis-tillation in water,distillation above water,diffusion distillation,re-distillation and simultaneous extraction dis-tillation,yields and components of essential oils were analyzed.Results showed that yield of essential oil by re-distillation was the highest.When using re-distillation to extract essential oil,yield was 1.101%based on mate-rial to water ratio of 8∶1 and distillation time of 2 h.In essential oil extracted by re-distillation,contents of β-pinene,4-terpineol,1,8-cineole and linalool met characteristic component requirements in Guangxi local stan-dard DB45/T 1064-2014.Results could provide references for industrial productions of B.frutescensessential oils.
