摘　　要：目的:分析翅萼石斛脂溶性化学成分。方法:采用石油醚超声提取法提取翅萼石斛的脂溶性成分,通过气相色谱-质谱联用法分析和鉴定化学成分(并用面积归一化法获得各化合物的相对质量分数)。结果:共鉴定出34种化合物,相对含量占总含量的71.859%,主要成分包括棕榈酸甲酯(3.913%)、邻苯二甲酸二丁酯(37.174%)、硬脂酸甲酯(2.526%)、十七烷(1.446%)、9-辛基十七烷(1.133%)、四十四烷(1.078%)、二十五烷(6.158%)、邻苯二甲酸二异辛酯(4.757%)、二十一烷(3.767%)。结论:为进一步确定翅萼石斛的化学成分和研究利用提供了一定的参考。Objective:To analyze the liposoluble components of Dendrobium Cariniferum. Method:The liposoluble components from Dendrobium Cariniferum was extracted by supersonic extraction method with petroleum ether. The relative contents were determined by GC-MS with area normalization method. Result:Thirty-four kinds of chemical constituents were isolated from the liposoluble parts of Dendrobium Cariniferum.The relative content was 71.859% of the total content. The main chemical ingredients were Methyl hexadecanoate(3.913%), Dibutyl phthalate(37.174%), Methyl octadecanoate(2.526%),Heptadecane(1.446%), 9-octyl heptadecane(1.133%), Tetratetracontane(1.078%), Pentacosane(6.158%), 1, 2-Benzenedicarboxylic acid, diisooctyl ester(4.757%), and Heneicosane(3.767%). Conclusion:The results provide profitable supplements and references for the further utilization and study of Dendrobium Cariniferum.
