果上叶挥发性成分研究

目的:研究果上叶中的挥发性成分。方法:利用有机溶剂-水蒸气蒸馏法提取果上叶挥发油,用GC-MS进行测定,结合计算机检索技术对分离化合物进行结构鉴定,应用色谱峰面积归一化法计算各成分的相对百分含量。结果:分离鉴定出38种化学成分,占挥发油总量91.448%,其中含量大于2%的分别为Z-9-十八烯醛18.075%、2,4-二叔丁基苯酚3.264%、棕榈酸5.413%、油酸25.079%、二十三烷6.344%、二十四烷3.768%、1-十八烯酸单甘油酯2.146%、亚油酸甘油酯4.953%、二十五烷4.332%、二十六烷3.387%、二十七烷3.841%、二十八烷3.102%。结论:本文采用气相色谱-质谱联用法对果上叶中的挥发性成分进行研究。

Determination of Chemical Constituents of Volatile Oil from Bulbophyllum odoratissimum

Objective:To study the chemical constituents of the volatile oil from Bulbophyllum odoratissi-mum.Method: The chemical compositions of the volatile oil of the plants which were obtained by organic-steam distillation with hexane were analyzed by GC-MS.The constituents were identified by their mass spectra.The rela-tive percentage of the oil constituents was calculated from the GC peak areas.Result: Thirty-eight kinds of chemical components were identified from B.odoratissimum.The amount of the identified com...
