| 摘 要： | 本文采用固相微萃取技术(SPME)收集成熟与未熟香蕉的挥发性物质,并运用气相色谱-质谱联用(GC-MS)对二者的化学成分进行种类和含量的比较分析。结果表明,两种香蕉果实的挥发性物质在种类和含量上存在明显差异,成熟香蕉中共检测出30种气味挥发性物质,而未熟香蕉中共检测出17种气味物质,且有多种化合物在成熟香蕉中存在而在未熟香蕉中未检测出。如成熟香蕉中的乙酸异戊酯、丁酸异丁酯、丁酸丁酯、2-庚醇-乙酸酯、异戊酸异戊酯、戊酸异戊酯和乙酸辛烯酯等7种物质的含量均明显高于未熟香蕉1以上。推测这些物质可能是成熟香蕉引诱桔小实蝇的活性物质。

| Abstract: | Ripe banana have significant attract effect to Bactrocera dorsalis.The volatile from ripe banana and unripe banana were extracted by solid phase microextraction(SPME) and the chemical composition and content of the volatile were analyzed by gas chromatography-mass spectrometry(GC-MS).The results showed that the chemical composition and content of the volatile from two banana listed above was different.30 volatile compounds were detected in ripe banana,while only 17 volatile compounds were detected in unripe... |
