热区2种菊科入侵植物精油化学成分的GC-MS分析

为了研究肿柄菊Tithonia diversifolia和胜红蓟Ageratum conyzoides的开发利用问题，用同时蒸馏萃取法(SDE)提取了2种植物精油，并用气质联用(GC-MS)技术进行定性和定量分析。结果表明：从2种入侵植物精油中共鉴定出66种化合物，2种植物精油中都能检测到3-己烯-1-醇、α-蒎烯、莰烯、β-蒎烯、α-松油烯、柠檬烯、异松油烯、α-胡椒烯、β-波旁烯、β-石竹烯、7-甲氧基-2,2-二甲基-2H-1-苯并吡喃、大香叶烯D、荜澄茄油烯醇、榄香醇、橙花叔醇、大香叶烯D-4-醇、石竹烯氧化物、库贝醇和Tau-杜松醇。2种入侵植物精油中分离出的多种成分在医药领域均有很高的价值。

GC-MS Analysis of Essential Oils from 2 Asteraceae Invasive Plants in Tropical Area

To study the development and utilization of Tithonia diversifolia and Ageratum conyzoides, constituents of essential oils extracted by simultaneous distillation and extraction (SDE) from these two plants were analyzed qualitatively and quantitatively by gas chromatography/ mass spectrometry (GC-MS). Results showed that 66 compounds were identified. The common components were 3-Hexen-1-ol, α-Pinene, Camphene, β-Pinene, α-Terpinene, Limonene, Terpinolene, α-Copaene, β-Bourbonene, β-Caryophyllene, Precocene I, Germacrene-D, Cubenol, Elemol, Nerolidol, Germacrene D-4-ol, Caryophyllene oxide, Cubenol and Tau Cadinol. Many constituents of essential oils from these 2 invasive plants could have a high value when used as medicines.
