| 摘要: |
| 采用水蒸气蒸馏法从大戟科蝴蝶果的根和果仁中提取挥发油,用气相色谱-质谱联用技术对挥发油化学成分进行分析,并应用面积归一化法测定各成分的相对百分含量。从根中鉴定出23种化合物,占总油量的100%,其主要成分为十六烷酸(18.74%)、(Z,Z)9,12-十八碳二烯酸(12.81%)、1,2-苯二羧酸双(2-甲基丙基)酯(10.59%)、二丁基邻苯二甲酸酯(7.42%)及二十四烷(6.72%)。从果仁中鉴定出17种化合物,占总油量的100%,主要成分为(E-)-9-十八碳烯酸(23.15%)、正十六烷酸(21.20%)、(Z,Z)-9,12-十八碳二烯酸(19.26%)及3-甲基十七烷(6.80%)。 |

| Abstract: |
| The essential oil extracted from the roots and nutlets of Cleidiocarpon cavaleriei were analyzed by GC-MS for the first time. The relative contents were determined by area normalization. 23 compounds were identified,which accounted for 100% of the essential oil of the roots. The major compositions were n-Hexadecanoic acid(18.74%);(Z,Z)-9,12-Octadecadienoic acid(12.81%),1,2-Benzenedicarboxylic acid,bis(2-methylpropyl)ester(10.59%),Dibutyl phthalatephthalate(7.42%)and Tetracosane(6.72%). 17 compounds were identified,which accounted for 100% of the essential oil of the nutlets. The major compositions were(E)-9-Octadecenoic acid(23.15%),n-Hexadecanoic acid(21.20%),(Z,Z)-9,12-Octadecadienoic acid(19.26%)and 3-Methyl-heptadecane(6.80%). |
