目的分析全缘叶绿绒蒿、五脉绿绒蒿和多刺绿绒蒿挥发油的化学成分。方法采用水蒸气蒸馏法获得挥发油,经GC-MS技术结合计算机检索对其化学成分进行分离和鉴定,用色谱峰面积归一化法计算各组峰的相对含量。结果从全缘叶绿绒蒿、五脉绿绒蒿和多刺绿绒蒿的挥发油中分别鉴定了25,42和53个化合物,占其各自总量的80.76%,73.34%和76.10%。结论3种绿绒蒿挥发油化学成分存在一定程度的差异,但其主要成分都为酯类物质。

OBJECTIVE To analyze the chemical constituents of essential oils from three different varieties of Meconopsis:Meconopsis integrifoli,Meconopsis quintuplinervia Rl and Meconopsis horridula H.METHODS The oils were extracted by steam distillation.The chemical compounds were separated and identified by GC-MS.The relative content of each component was determined by area normalization.RESULTS Twenty-five,forty-two and fifty-three compounds from M.integrifolia Mch,M.quintuplinervia R and M. horridula were identified respectively in turn.The ratios of identification of total compounds were 80.76%, 73.34% and 76.10%,respectively.CONCLUSION There are some differences among three species of Meconopsis,but the main ingredients are esters.
