| Abstract: | 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. |
