臭牡丹挥发油化学成分的GC-MS分析

Experimental Study on Chemical Constituents of the Volatile Oil from Different Parts of Clerodendrum Bungei

目的:研究臭牡丹不同部位的挥发油成分。方法:用水蒸汽蒸馏法分别提取臭牡丹叶和花的挥发油,通过GC-MS分析方法对这两个部位挥发油的化学成分进行对比研究,并用面积归一化法获得各化合物的相对质量分数。结果:从臭牡丹花挥发油中鉴定了28个化合物,主要成分为棕榈酸(29.52%)、亚油酸(15.26%)、二十七烷(9.27%)和叶绿醇(8.99%);从臭牡丹叶挥发油中确定了20个化合物,含量最多的为叶绿醇(32.79%),其次为芳樟醇(5.95%)。该植物花和叶部位共测定出5个相同的化合物,分别为芳樟醇、α-松油醇、邻苯二甲酸二异丁酯、棕榈酸和叶绿醇。结论:臭牡丹的挥发油成分中含有大量具有明显生物活性的挥发油成分,可为综合开发利用臭牡丹提供科学依据。

Objective：to study and detect volatile oil compounds in different parts of Clerodendrum Bungei.Methods：the volatile oil from the flowers and leaves of Clerodendrum bungei was obtained by steam distillation and analyzed by gas chromatography-mass spectrometry（GC-MS）.The relative contents were determined by area normalization.Results：28 compounds were identified from the leaves volatile oil,in which the major constituents were palmitic acid（29.52%）,linoleic acid（15.26%）,heptacosane（9.27%）and phytol（8.99%）.For the flowers volatile oil,20 compounds were identified,and the major component was phytol（32.79%）,followed by linalool（5.95%）.5 compounds were found in both flowers and leaves volatile oil,including linalool,α-terpinol,Diisobutyl phthalate,palmitic acid and phytol.Conclusion：The chemical and scientific basis was exposed and provided for the comprehensive utilization of Clerodendrum bungei.
