罗布麻叶挥发油的气相色谱-质谱分析

用挥发油提取器提取了罗布麻叶中挥发油,测得含量为w=0.02%。并采用气相色谱-质谱联用技术对罗布麻的挥发性成分进行了分离鉴定。分离出52种成分,共确认了其中25种成分,占挥发油总含量的85.38%。采用峰面积归一化法确定了各成分的相对含量,其中主要成分为氧化石竹烯(10.57%)、1-α-萜品醇(10.38%),苯甲酸-3-己烯酯(6.45%)、3,7,11,15-四甲基-2-十六碳烯-1-醇(5.99%)、大马酮(5.85%)、反式-金合欢醇(5.27%)、2-甲基-5-异丙基苯酚(4.77%)、长叶薄荷酮(4.25%)。

Analysis of Volatile Oil From Apocynum venetum L. by Gas Chromatography-Mass Spectrometry

The volatile oil was extracted from Apocynum venetum L.by using extracted device of volatile oil. The content of the volatile oil was 0.02%. The chemical components of the volatile oil were examined by gas chromatography mass spectromentry (GC/MS), 52 constituents were separated and 25 compounds were identified. The identified compounds consitute more than 85.38% of the total ion current. The relative content of the components were determined with peak area normalization method, the major constituents of the volatile oil are caryophyllene oxide(10.57%), 1 α terpineol(10.38%), 3 hexen 1 olbenzoate(6.45%), 3,7,11,15 tetramethyl 2 hexadecen 1 ol(5.99%), β damascenone( 5.85 %), trans farnesol(5.27%), 2 methyl 5 (1 methylethyl)phenol(4.77%), pulegeone( 4.25 %).
