顶空固相微萃取-气相色谱质谱分析蓝莓粗提物中的挥发性成分

Analysis of the volatile chemical composition of blueberry (Elliott) extracts by HS-SPME-GC-MS method

摘要: 通过醇提法提取中国栽培蓝莓品种中的活性物质,采用顶空固相微萃取-气相色谱质谱法（HS-SPME-GCMS）分析了蓝莓粗提物中的挥发性成分,利用面积归一化法定量组分含量。检测出37个化学成分,鉴定了其中的33个化学成分。其中醇类化合物占24.15%,其次是烷烃类化合物,占17.05%,烯烃类化合物占13.61%,酯类化合物占11.97%,还有8.80%的苯和苯酚类化学物,醛、酸、酮类化合物分别为8.79%、8.21%与7.42%。

Abstract: The active substances of Chinese culture blueberry varieties (Elliott) were extracted by ethanol, and its volatile components were analyzed by Head Space Solid Phase Micro-extraction Gas Chromatography Mass Spectrometry (HS-SPME-GC-MS) . The peak area normalization method was used for quantitative analysis. 37 chemical composition were detected, and 33 chemical composition were identified. Alcohol (24.15%) , alkane (17.05%) , olefin (13.61%) , ester (11.97%) , benzene and phenol (8.80%) , aldehydes (8.79%) , acid (8.21%) and ketone (7.42%) were included in the 33 kinds of compound.
