‘长营’橄榄果实挥发性成分分析

Study on Volatile Compounds in Fruit of Canarium album ‘Changying’

采用固相微萃取法和气相色谱-质谱联用法,对福建闽侯地区的优良橄榄品种‘长营’橄榄(Canarium album ‘Changying’)果实的香气成分进行分析,分离出22个峰,确认了22种化学物名称及其相对含量。结果表明:‘长营’橄榄挥发油主要成分为石竹烯、八氢-7-甲基-3-亚甲基-4-异丙基-1H-五环[1,3]三环[1,2]苯、1,2,3,5,6,8a-六氢-4,7-二甲基-1-异丙基萘、古巴烯、α-石竹烯、丁基羟基甲苯、β-蒎烯、α-毕澄茄油烯等,其中石竹烯含量最高,达42.40%。比较‘冬节圆’橄榄、‘三棱’榄橄的挥发物成分,表明橄榄挥发物的主要成分为烯类,但成分各不相同。可见不同品种或不同产地的橄榄香气成分差异较大。

The volatile compounds in the fruit of Canarium album ＇Changying＇, which is Fujian Minhou＇s superior variety, were extracted by SPME and analyzed by Capillary GC-MS method. By Capillary Chromalography, more than 29 peaks were isolated and identified. The results showed that the main volatile components were Caryophyllene, octahydro-7-methyl-3-methylene-4- （1-methylethyl）-,Naphthalene, 1,2,3,5,6,8a-（1-methylethyl）-,Naphthalene, 1,2,3,5,6,8a-hexahydro- 4,7-dimethyl-1-（1-methylethyl）-, Copaene, a-Caryophyllene, Butylated, H-ydroxytoluene, Cyclohexane, 1-ethenyl-l-methyl2,4-bis（1-methylethenyl）-,a-Cubebene. Caryopsyllene content was the highest, accounted for 42.40%. Comparing with the analysis results of Canarium album ＇ Changying＇ to Canarium album ＇Dongjieyuan＇ and Canarium album ＇Sanleng＇, we found that the main component was terpenes, but the ingredients were different. Obviously, the volatile components of Canarium album from different trains and regions were different.
