摘　　要：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%)。The volatile oil was extracted from vice of volatile oil. The content of the volatile Apocynum venetum L. by using extracted deoil 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-olben- zoate (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%).
