破布叶叶片中挥发油的化学成分研究

Chemical Constituents of Volatile Oil from Leaves of Microcos paniculata L.

用水蒸气蒸馏法提取破布叶叶片中的挥发油,得油率为0.63 %,采用GC-MS进行化学成分分析,首次鉴定出15种化合物,占总离子流出峰面积的99.99 %。破布叶叶片中挥发油主要成分为烃类和脂肪酸类物质,主要有2-甲氧基-4-乙烯基苯酚(18.12 %)、二十八烷(11.77 %)、十六烷酸(11.29 %)、二十五烷(10.32 %)、二十七烷(8.61 %)、2,3-二氢苯并呋喃(6.29 %)、四十四烷(5.99 %)和三十六烷(5.51 %)。

The volatile oil from leaves of Microcos paniculata L. was obtained by steam distillation. The chemical constituents were separated and identified by GC-MS. Relative contents of volatile oil were determined by peak area normalization. The yield of oil by steam distillation was 0.63 %, and 15 compounds from the volatile oil were separated and identified, which account for 99.99 % of total volatile oils. The main chemical constituents were 2-methoxy-4-vinylphenol （18.12 % ）, octacosane （11.77 % ）, n-hexadecanoic acid （ 11.29 % ）, pentacosane （ 10.32 % ） , heptacosane （ 8.61% ）, 2,3-dihydro-benzofuran （ 6.29 % ）, tetratetracontane（5.99 % ） and hexatriacontane （5.51% ）.
