摘要
采用亚临界丁烷对崖柏根部挥发油进行提取,在单因素试验基础上,采用响应面法对其提取工艺进行优化,并利用气相色谱-质谱联用仪(GC-MS)对挥发油进行成分分析。结果表明:最佳萃取条件为萃取时间48 min、萃取温度35℃、料液比1∶21(g/mL),在此条件下挥发油得率最高为10.10%;GC-MS分析显示挥发油中共有46种成分,萜类化合物为主要成分,其中含量较高的分别为雪松醇(43.53%)、(+)-花侧柏烯(9.00%)和罗汉柏烯(7.92%)。
The volatile oil from Thuja sutchuenensis Franch.was extracted by subcritical butane extraction method and optimized by response surface method based on the single factor test,and the components of the volatile oil were analyzed by gas chromatography-mass spectrometry(GC-MS).The results showed that the optimal extraction conditions were extraction time 48 min,extraction temperature 35 ℃,solid-liquid ratio 1 ∶21(g/mL).Under these conditions,the highest yield of volatile oil was 10.10 %.GC-MS analysis showed that there were 46 components in the volatile oil and the terpenoids were the main components,of which cedrol(43.53 %),(+)-platycladus orientalis(9 %)and luohanbaiene(7.92 %)were the higher ones.
