南京紫金山不同植物群落中VOCs的组成
Analysis of compositions and changes of VOCs in different plant communities of Zijinshan Mountain in Nanjing
摘要
Abstract
TCT-GC/MS was used to analyze the ingredients of volatile organic compounds (VOCs) of 4 typical plant communities of Zijinshan Mountain in Nanjing, We totally detected 7 compositions, including terpenes, alcohols, kctones, aldehydes, esters, alkanes and phenols. The main volatile constituents in spring and summer were the terpenes and the alcohols, their average relative contents were 28. 65 ％, 38. 51％ respectively; the main volatile constituents in autumn and winter was the alkanes. Its average relative content accounted for 51.18 ％ of the volatile mass quantity. The relative contents of the other VOCs were low. The order of relative contents of terpenes, alcohols and esters in different seasons were as fol]ows: summer ＞ spring ＞ autumn ＞ winter, and the order of relative content of alkanes in different sea sons was winter ＞ autumn ＞ spring ＞ summer. However, the regularity for change of the other VOCs was different in different communities. Tihe relative content of terpenes of Liquiclambarformosana + Acer buergerianum community was the highest in spatial, and its relative contents was 40. 27 ％, the next was Pinus massoniana + L. formosana community (31.36 ％ ), Quercus acutissima + Q. variabilis community (25 17％ ) ,P. massoniana + Q. acutissima community ( 18.01％ ); The relative contents of alcohols of P. massoniana + L. formosana community was the highest in summer and autumn, and its relative content was 43.92 ％, whereas in winter and spring, the relative contents of alcohols of P.massoniana + Q. acutissimacommunity was the highest, and its relative content was 31.25 ％.关键词
