摘要
利用水蒸汽蒸馏法、两相溶剂萃取法提取下田菊(Adenostemma lavenia(L.)O.Ktze.)地上部分的挥发油,提取10h的挥发油得率为0.990%。采用毛细管气相色谱-质谱联用(GC-MS)技术结合计算机检索对该挥发油的化学成分进行了分析和鉴定,采用色谱峰面积归一化法计算了各成分的相对含量。从挥发油中共分离出36个峰,鉴定了其中的35种成分,占总量的99.56%,其中α-荜澄茄油烯(32.62%)、石竹烯(24.97%)和γ-榄香烯(5.53%)为主要成分,此外α-石竹烯(3.97%)、α-恰米烯(3.57%)、双环[4,3,0]-7-亚甲基-2,4,4-三甲基-2-乙烯基-壬烷(3.41%)、γ-萜品烯(3.07%)、d-柠檬烯(2.57%)、α-蒎烯(2.49%)及2-蒈烯(2.28%)的含量也较高。
The volatile oil was obtained by steam distillation, followed by solvent extraction from the aerial parts ofAdenostemma lavenia （L.） O. Ktze.. The yield of the volatile oil reached 0.990% after steam distillation for 10 hours. The constituents of the obtained volatile oil were analyzed by GC-MS, and their relative contents were determined by peak area normalization. Thirty-six peaks were detected from the volatile oil, of which 35 chemical compounds were identified, accounting for 99.56% of the volatile oil. The main components were α-cubebene （32.62%）, caryophyllene （24.97%） and γ-elemen （5.53%）. Some other monoterpenes and sesquiterpenes, such as α-caryophyllene （3.97%）, α-chamigrene （3.57%）, bicyclo [4,3,0]-γ-methylene-2,4,4-trimethyl-2-vinyl nonane （3.41%）, γ-terpinen （3.07%）, d-limonene （2.57%）, α-pinene （2.49%） and 2-carene （2.28%） were also identified.
