摘要

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。

Abstract

Objective: To study the chemical constituents of the volatile oil from Bulbophyllum odoratissimum . 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 relative 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 components was accounted for 91.448% of all the volatile oil. The constituents whose relative content was more than 2% were determined as Z-9-octadecenal (18.075%)

4-Di-tertbutylphenol (3.264%)

palmitic acid (5.413%)

oleic acid (25.079%)

tricosane (6.344%)

tetracosane (3.768%)

1-Monoolein (2.416%)

1-monolinolein (4.953%)

pontacosane (4.332%)

hexacosane (3.387%)

heptacosane (3.841%)

octacosane (3.102%). Conclusion: The composition of volatile oils from B. odoratissimum by GC-MS.
