摘要
分别采用微波水蒸气蒸馏法(MHD,微波功率300 W,固液比1∶10,蒸馏时间1 h)和水蒸气蒸馏法(HD)提取山东披萨草挥发油,利用气相色谱-质谱(GC/MS)联用技术和保留指数比较法分析了挥发油的化学成分。从MHD法披萨草挥发油中鉴定出42种化合物,占挥发油总量的99.35%,主要成分为香芹酚(67.85%)、麝香草酚(16.18%)和邻伞花烃(3.00%)。从HD法披萨草挥发油中鉴定出39种成分,占挥发油总量的99.10%,主要成分为香芹酚(69.78%)、麝香草酚(16.08%)和红没药烯(2.01%)。
Volatile oils of Origanum vulgare L.in Shandong were separated by using microwave-assisted hydrodistillation(MHD 300 W,solid-to-liquid ratio 1∶10,microwave hydrodistillation time 1 h) and hydrodistillation(HD).The chemical components of the oils were identified by GC/MS technique and comparison of retention indices.Forty-two components were characterized,representing 99.35% of total MHD oil.Major components are carvacrol(67.85%),thymol(16.18%),and o-cymene(3.00%).Thirty-nine components were identified,representing 99.10% of total HD oil.Major components were carvacrol(69.78%),thymol(16.08%),and β-bisabolene(2.01%).
