| 摘 要： | 讨论了采用微波辐照从山苍子中提取制备柠檬醛，精油的得率较传统的直拉水蒸气蒸馏法平均提高2.48%以上。用程序升温毛细管柱气相色谱归一化法测定山苍子精油中的柠檬醛，获得了山苍子精油中柠檬醛含量为68.64%，回收率为101.3%，相对标准偏差为0.28%，线性相关系数为0.9997，准确性与内标法相一致的实验结果，而且操作较内标法和GB11424－89法更为方便。

| Abstract: | Citral is extracted from Litsea cubeba with microwave radiation.Content of essential oil extracted from L.cubeba fruit using microwave radiation is on an average 2.48% higher than that using traditional direct steam distillation.Adopting gas chromatography with temperature programming,citral content in the oil was determined to be 68.46%,at recovery 101.3%,relative standard deviation 0.28%, linear relative coefficient 0.9997,which are in good agreement with those measured by internal standard method,but the operation is simpler than both the internal standard and GB 11424-89 methods. |
