鬼针草叶片精油化学成分的GC-MS分析

摘要

To study the volatile chemical components of Bidens bipinnata L.from tropic forestry of Yun-nan,the essential oil from Bidens bipinnata L.leaves was extracted by simultaneous distillation and extraction (SDE)method.The chemical components of essential oil were analyzed by gas chromatography-mass spectrom-etry(GC-MS).There were 61 compounds identified from Bidens bipinnata L.leaves.The main components were terpenoids and green leaf volatiles.The most abundant compound was myrcene (20.07%),followed byα-pinene (11.82%)andβ-caryophyllene (9.14%).%为了研究云南热带林区鬼针草挥发性化学成分，采用同时蒸馏萃取法（SDE）提取鬼针草叶片精油，利用气相色谱-质谱联用仪分析精油的化学成分。结果表明，从鬼针草叶片中共分离出61种化合物，主要是萜类化合物和绿叶挥发性物质，相对含量最多的是大香叶烯（20.07％），其次是α-蒎烯（11.82％）和β-石竹烯（9.14％）。
