摘  要:
[目的]优化香柏精油提取工艺。[方法]采用盐析协同水蒸气蒸馏法对香柏精油的提取工艺进行研究。分别考察NaCl的浓度、液料比、浸泡时间以及蒸馏时间对香柏细枝叶精油提取率的影响。[结果]提取香柏精油的最佳工艺条件为:NaCl浓度4%,料液比1∶15(g∶ml),浸泡时间6 h,蒸馏时间3 h;在此条件下香柏精油提取率1.80%。[结论]该方法简单可靠,可用于工业化生产。

摘  要:
[Objective] To optimize the extraction technology of essential oil from Thuja occidentalis L.[Method] The methods of salting-out and steam distillation were adopted to study the extraction technology and inspect the effect of NaCl concentration,liquid-solid ratio,soaking time and distillation time on the extraction rate of essential oil.[Result] The optimum extraction conditions were: 4% NaCl,1∶15(g∶ml) solid-liquid ratio,6 h soaking time and 3 h distillation time.Under these conditions,the extraction rate was 1.80%.[Conclusion] The method was simple and reliable,which was applicable for industrial production.
