青蒿;挥发油成分分析;气相色谱-质谱(GC/MS);同时蒸馏萃取法
摘  要:
采用同时蒸馏萃取法提取产自河北卢龙地区青蒿中的挥发油,测得青蒿挥发油含量为8.8%;并用气相色谱-质谱联用技术进行分离鉴定和计算机质谱图库检索,鉴定出了23种化学组分,占总挥发性物质总含量76.56%;应用峰面积归一化法确定了各成分的相对含量。结果表明:同时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(37.16%)、桉叶油素(11.20%)、3,3,6-三甲基-1,5-庚二烯-4-醇(4.49%)、石竹烯(4.43%)、大根香叶烯D(3.35%)等。

摘  要:
The volatile oil was extracted from the Artemisia apiacea Hance of Lulong area in Hebei Province by using simultaneity distillation extraction method(SDE).The content of the volatile oil was 8.8%.23 compounds were identified by GC/MS.The contents of the identified compounds make up 76.56% 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)(37.16%)、Eucalyptol(11.20%)、3,3,6-Trimethyl-1,5-heptadien-4-ol(4.49%)、Caryophyllene(4.43%)、Germacrene D(3.35%)
