滇黔金腰、大叶金腰和锈毛金腰挥发油的化学成分

从贵州省宽阔水自然保护区采集滇黔金腰、大叶金腰和锈毛金腰,采用水蒸汽蒸馏法提取挥发油,用气相色谱—质谱联用技术对挥发油化学成分进行分析,共鉴定出85种成分,主要为十六烷酸、烷烃类、肉豆蔻酸和叶绿醇等化合物。其中,在滇黔金腰中共鉴定出48种化学成分,主要有十六烷酸(10.29%)和月桂酸(7.54%)等;在大叶金腰中共鉴定出50种化学成分,主要有邻苯二甲酸二(2-乙基己)酯(10.91%)和二十七烷(7.29%)等;在锈毛金腰中共鉴定出58种化学成分,主要有十六烷酸(12.66%)和三十二烷(8.15%)等。不同种金腰属植物挥发油的主要成分种类比较接近,但各自挥发油化合物组成又都含有其特有化学成分。

Chemical constituents of volatile oils in Chrysosplenium cavaleriei,C.macrophyllum and C.davidianum

The volatile constituents in Chrysosplenium cavaleriei,C.macrophyllum and C.davidianum from Kuankuoshui Nature Reserve in Guizhou Province were extracted with steam distillation and analyzed by GC-MS. Eighty-five different compounds were identified from the samples,in which the main compounds were Hexadecanoic acid,Alkanes,Myristic acid and Phytol. There were 48 compounds in C.cavaleriei,in which the main compounds were Hexadecanoic acid(10.29%)and Lauric acid(7.54%). There were 50 compounds in C.macrophyllum,in which the main compounds were Octoil(10.91%)and Heptacosane(7.29%). There were 58 compounds in C.davidianum,in which the main compounds were Hexadecanoic acid(12.66%)and Dotriacontane(8.15%). The results showed that the main compounds of the volatile constituents in the 3 species in Chrysosplenium were similar,but there were some unique volatile constituents in them respectively.
