【摘要】 采用普通水蒸气蒸馏萃取法,对产自河北卢龙地区青蒿中的挥发油进行提取,测得青蒿挥发油含量为7.2%;并用气相色谱-质谱(GC/MS)联用技术进行分析鉴定,结合计算机质谱图库检索技术对分离的化合物进行结构分析,鉴定21种化学组分,占总挥发性物质总含量的74.02%。应用峰面积归一化法确定了各成分的相对含量。结果表明:普通水蒸气蒸馏萃取法提取的挥发油中主要含有N,N?-双(2,6-二甲基-6-亚硝基)庚-2-烯-4-酮(29.29%)、桉叶油素(7.16%)、二十六烷(5.93%)、二十五(碳)烷(5.1%)等。更多还原

【Abstract】 The volatile oil was extracted from the Artemisia apiacea Hance from Lulong area in Hebei Province by using direct distillation extraction method(DDE).The content of the volatile oil was 7.2%.21 compounds were identified by GC/MS.The contents of the identified compounds made up to 74.02% of total volatile substances.The relative content of the components were determined with area normalization method.The main components of volatile substances are N,N′-Bis(2,6-dimethyl-6-nitrosohept-2-en-4-one)(29.29%)、Eucalyptol(7.16%)、Hexacosane(5.93%)、Pentacosane(5.1%),etc.更多还原
