摘要
利用固相微萃取法(SPME)和气质联用(GC-MS)技术对中国产黑珍珠莲雾Syzyzgium samarangense果实5个不同发育阶段的挥发物进行分析.共检测出44种物质,主要包括萜烯类、醇类、酮类和酯类,其中仅有8种物质是各阶段所共有的,它们是(-)-α-烯、β-石竹烯、á-芹子烯、à-芹子烯、α-依兰油烯、δ-杜松烯、2,4',5-三甲基二苯基甲烷、邻苯二甲酸二异丁酯.酮类主要包括莰酮和反式-β-紫罗酮-5,6-环氧化物,酯类化合物包括邻苯二甲酸二异丁酯和乙酸异丁酯.在果实的不同发育阶段,挥发物成分与含量差异很大,萜烯类的相对含量随着果实的成熟而减少,莰酮和邻苯二甲酸二异丁酯的含量随着果实的成熟逐渐升高,反式-β-紫罗酮-5,6-环氧化物与乙酸异丁酯仅在成熟期才大量出现.
The volatile constituents from five different developmental stages of black pearl wax apple fruit(Syzyzgium samarangense) growing in China were analysed by solid phase microextraction(SPME) and gas chromatography-mass spectrometry(GC-MS).Forty-four compounds were identified in wax apple,among which volatiles,terpenoids,alcohols,ketones and esters were the major components,among which eight compounds were observed at all five developmental stages,i.e.,(-)-α-copaene,β-caryophyllene,á-selinene,à-selinene,α-muurolene,δ-cadinene,2,4′,5-trimethyl diphenylmethane,1,2-benzenedicarboxylic acid bis[2-methylpropyl] ester.Ketones of wax apple fruit included camphor and trans-beta-ionone-5,6-epoxide,esters components comprised 1,2-benzenedicarboxylic acid bis[2-methylpropyl] ester and acetic acid,2-methylpropyl ester.The volatile compositions from five developmental stages of the fruit were quite different.The relative contents of terpenoids gradually decreased,and those of camphor and 1,2-benzenedicarboxylic acid bis[2-methylpropyl] ester increased along with the fruit ripening.Trans-beta-ionone-5,6-epoxide and acetic acid,2-methylpropyl ester were only found at ripe stage.
