Analysis of volatiles from fruit and leaf of insect-resistant and insect-susceptible chestnut cultivars with GC-MS
摘要
Abstract
【Objective】In order to compare the components and their contents of volatiles in insect-resistant and insect-susceptible chestnut varieties,【Method】volatiles extracted from fruits and leaves of the insect-resistant variety,Heyuan oil chestnut(HC) and the susceptible variety,Nongda No.1 chestnut(NC) were analyzed with the application of gas chromatography mass spectrometry.【Result】111,142,138 and 134 kinds of components were identified respectively.HC fruits had 32 components whose contents were over 0.5%,while HC leaves had 30,and both NC fruits and leaves had 20,The components with higher content accounted for 83.03%,84.96%,81.73% and 83.95% respectively of the total,mainly as green leaf volatiles,aromatics,monoterpenes,sesquiterpenes and heterocyclics.The major components of HC fruit volatiles were(E)-2-Hexenal(10.59%),1-Hexanol(10.42%),Furfural(8.07%),Benzeneacetaldehyde(5.63%) and Benzaldehyde(4.76%);in HC leaf,were 2-ethoxy-Propane(19.73%),(Z)-3-Hexen-1-ol(14.4%),1-Hexanol(10.23%),(E)-2-Hexen-1-ol(6.83%) and β-Eudesmol(4.76%);in NC fruit,were 2-ethoxy-Propane(49.71%),Furfural(4.11%),(Z)-3-Hexen-1-ol(3.89%),β-Eudesmol(3.19%) and Benzeneacetaldehyde(2.44%);and in NC leaf,the major components were(E)-2-Hexenal(20.18%),1-Hexanol(15.28%),(E)-2-Hexen-1-ol(12.01%),2-ethoxy-Propane(6.82%) and Benzyl alcohol(6.16%).The content of green leaf volatiles and aromatics in HC fruit was higher than that in NC fruit,accounting for 32.55% and 13.79% respectively in HC fruit,while only 9.96% and 5.23% respectively in NC fruit.The three characteristic compounds of HC fruit volatiles,(E)-2-Hexenal,1,2,3,4,4a,5,6,7-octahydro-4a-methyl-2-Naphthol and 3-Pentanol were abundant,accounting for 10.59%,4.66% and 3.53% respectively of the total.However,HC fruit volatiles had no 2-ethoxy-Propane,(Z)-3-Hexen-1-ol and Toluene which accounted for 49.72%,3.89% and 2.32% respectively in NC fruit volatiles.【Conclusion】 The study suggested that the composition of volatiles from insect-resistant and insect-susceptible chestnut varieties were quite different.关键词
