中文摘要:
|
分别采用顶空固相微萃取(SPME)和水蒸气蒸馏法(SD)提取金钗石斛花挥发性成分,用气相色谱-质谱联用技术(GC-MS)对其进行成分分析,采用峰面积归一化法计算各组分的相对质量分数。两种方法分别鉴定出63种和24种化合物,占总挥发性成分的80.49 %和54.92%。其中,SPME法提出的挥发性成分质量分数较高的有柠檬烯(25.87%)、四氢柠檬醛(11.1%)、松油烯(8.7%)、2-呋喃甲醛(6.51%)、甲酸己酯(2.12%)等;SD法提出的挥发性成分质量分数较高的有亚油酸(36.92%)、庚烷(7.69%)、肉豆蔻酸(3.51%)、亚油酸甲酯(2.12%)等。

The volatile oil of the flower ofDendrobium nobile Lindl. were extracted by SPME and SD and then analyzed by GC-MS. The relative percentage of volatile oil constituents was calculated from the GC peak areas. 63 and 24 compounds extracted by SPME and SD were identified respectively,which represent 80.49% and 54.92% of the total volatile oil. The main components extracted by SPME and SD were limonene(25.87%),tetrahydrocitral(11.1%),terpinene(8.7%),2-furancarboxaldehyde(6.51%),hexyl formate(2.12%),and linoleic acid(36.92%),heptane(7.69%),tetradecanoic acid(3.51%),methyl linoleate(2.12%),etc.
