【摘要】 采用水蒸气蒸馏法分别提取野艾与家艾茎、叶中的挥发油,用气相色谱-质谱法(GC/MS)对其挥发性成分进行分析,并分别比较家艾和野艾茎叶挥发油的化学成分的种类和含量差异。结果表明:艾蒿的茎叶挥发油中共分离出109种挥发性成分,野艾和家艾的茎叶中共有12种相同的挥发性成分,其中主要的挥发性成分是萜类化合物,家艾、野艾茎中萜类化合物含量分别为66.352%,51.473%,而家艾、野艾叶中萜类化合物含量约为74.336%,73.186%。通过主成分分析可知家艾和野艾茎叶的挥发性物质主要是植酮、金合欢烯、蒎烯、桉叶油醇、樟脑、石竹烯、香叶烯。更多还原

【Abstract】 The volatile oil of domestic and wild Artemisia argyi Levl.et Vant was extracted with steam distillation,and the chemical compositions were analysed by GC-MS,the chemical composition difference of the volatile oil between the domestic and wild A.argyi Levl.et Vant were compared as well.The results showed that 109 kinds of volatile components were isolated from the stems and leaves of A.argyi Levl.et Vant,and the domestic and wild Artemisia argyi Levl.et Vant shared 12 kinds of volatile components.The main volatile components were terpenoid,and their total contents in the stems of domestic and wild Artemisia argyi Levl.et Vant was 66.352% and 51.473% respectively.While the total contents of terpenoid in the leaves of domestic and wild A.argyi Levl.et Vant were 74.336% and 73.186%,respectively.Trough the principle component analyses,the main volatile chemicals of domestic and wild A.argyi Levl.et Vant were the plant ketone,farnesene,pinene,eucalyptus oil,camphor,caryophyllene,and myrcene.更多还原
