摘要:

采用固相微萃取- 气相色谱- 质谱联用方法分析甘肃主产苦瓜的挥发性成分,共鉴定出83 种成分。结果显示,苦瓜挥发性成分主要为醛类、醇类、烯烃类、烷烃类化合物。其中醛类物质共18 种、醇类15 种、烯烃类11 种、烷烃类8 种,各类物质相对含量分别占总挥发性成分的37.46%、37.16%、7.02%、2.92%。

关键词: 苦瓜, 挥发性成分, 固相微萃取-气相色谱-质谱联用

Abstract:

Freshly harvested fruits of bitter melon grown in Gansu province were analyzed for volatile composition by SPMEGC- MS. A total of 83 volatile components were identified and aldehydes, alcohols, alkenes and alkanes were the dominant volatile constituents. Totally 18 of aldehydes, 15 of alcohols, 11 of alkenes and 8 of alkanes were identified, accounting for 37.46%, 37.16%, 7.02% and 2.92% of total volatile components, respectively.

Key words: bitter melon, volatile composition, solid phase microextraction-GC-MS (SPME-GC-MS)
