摘　　要： 采用热脱附-气相色谱/质谱(TCT-GC/MS)联用技术,对动态顶空密闭循环吸附捕集的菠萝果皮及果肉的挥发物进行了检测,结果表明:菠萝果皮与果肉的香气中富含酯类化合物、尤其是甲酯类成分,含量最高的均为己酸甲酯、分别达到45.66%和64.45%;果皮挥发物中的2-甲基丁酸甲酯相对含量为8.03%、辛酸甲酯相对含量为6.44%,均比果肉中的含量(分别为6.50%和3.51%)高;果肉挥发物中未检出非酯类成分,而在果皮挥发物中检测到2,5-二乙烯基四氢吡喃(9.07%)和少量甲酸乙酸酐(0.87%)。 Fragrances from peel and inner-fruit of pineapple （Ananas comosus （L.） Merr.） were closely and circularly head-space sampled within adsorptive tubes, then analyzed by thermal-desorption cryo-trapping gas chromatography / mass spectrometry （TCT-GC/MS）. Results showed that esters, especially methyl esters, were both high contained in the two samples. The contents of methyl caproate in peel （45.66%） and inner-fruit （64.45%） were both the highest among total volatile chemicals. In peel volatiles, the contents of butyric acid, 2-methyl-, methyl ester and caprylie acid, methyl ester were 8.03% and 6.44%, which were higher than those in inner-fruit （6.50% and 3.51%）. 2,5-Divinyltetrahydropyran （9.07%） and Acetic acid, anhydride with formic acid （0.87%） were detected in peel volatiles but did not in inner-fruit volatiles.
