摘要
使用75μm Carboxen/PDMS和100μm聚二甲基硅氧烷(polydimethylsiloxane,PDMS)两种萃取头提取紫花芒果成熟时果肉和果皮的香气成分,并用气质联用仪定性定量分析香气成分。使用75μmCAR/PDMS萃取头检出果皮香气成分26种,占总挥发物的98.71%,萜类成分占98.49%,挥发性成分相对含量较高的是萜品油烯(44.20%);果肉香气检出21种挥发物,占总挥发物的99.29%,其中萜类占97.82%,相对含量较高的是对伞花烃(55.45%)。使用100μmPDMS萃取头检出果皮香气中22种挥发物,占总挥发物的98.51%,萜类成分占98.14%,其中相对含量较高的是萜品油烯(68.45%);果肉香气中检出15种挥发性成分,占总挥发物的97.68%,萜类占96.69%,相对含量较高的是萜品油烯(79.18%)。紫花芒果更适合使用75μmCarboxen/PDMS提取香气成分进行分析,且果皮中的香气成分多于果肉中,主要是萜类成分。
The volatile components in ripening fruit peel and pulp of mango （Mangifera indica L. var Zihua） were extracted with 100 μm PDMS or 75 μm Carboxen/PDMS fibres prior to GC-MS analysis. Twenty-six volatile components were identified in mango peel extracted with 75 la m Carboxen/PDMS fibre, accounting for 98.71% of total volatile components. Terpenes contributed to 98.49% of identified components, among which terpinolene constituted a major fraction, accounting for 44.20%. Totally 21 components were detected in mango pulp, occupying 99.29% of total volatile components. Terpenes made a contribution of 97.82%, in which p-cymene was a dominant compound （55.45%）. However, only 22 volatile components were identified in mango peel extracted with 100 μm PDMS fibre, which accounted for 98.51% of total volatile components, comprising 98.14% of terpenes and the content of terpinolene was 68.45%. Fifteen volatile components were found in mango pulp, the total relative content 97.68%, and the content of terpenes 96.69% with the dominant terpinolene of 79.18%. Therefore, 75 μm Carboxen/ PDMS fibre provides a much more suitable tool for the extraction of volatile components in mango fruits and the peel seems to contain more volatile components than the pulp in quantity, and the main volatile is terpenes.
