摘 要: 采用动态顶空采集法和热脱附-气质联用技术ꎬ对不同季节和一天内不同时间点樟树叶片释放的
挥发性有机物(VOCs)成分含量及其变化规律进行了分析ꎮ 结果表明:全年樟树叶片释放的 VOCs 共计 78
种ꎬ其中萜烯类(19 种)和烷烃类(18 种)化合物种类较多ꎻ32 种樟树叶片释放的挥发性成分相对含量在不
同季节存在显著差异(P<0.05)ꎻ3 月份释放的 VOCs 种类最为丰富ꎬ萜烯类化合物相对含量最高(43.49%)ꎬ
主要为 1 ̄石竹烯、D ̄柠檬烯和 α ̄蒎烯ꎬ其他月份释放的 VOCs 则以烷烃类和醇类为主ꎻ春季ꎬ樟树叶片在绝
大多数时间点释放 VOCs 以萜烯类化合物为主ꎬ且早上 8:00 释放的萜烯类化合物相对含量最大ꎮ 综上结果
认为ꎬ樟树是营造保健型生态园林的理想树种ꎬ其叶片释放的 VOCs 中富含多种对人体健康有益的萜烯类
化合物ꎬ春季的早晨是进行森林康养活动的最佳时间ꎮ

Abstract: Volatile organic compounds (VOCs) were collected in different seasons and different times of the day by dy ̄
namic headspace air ̄circulation methodꎬ and the relative contents and the change laws were also analyzed using the ther ̄
mal desorption system gas chromatography/ mass spectrum (GC ̄MS). The results were as follows: Cinnamomum campho ̄
ra leaves released 78 types of VOCs during the whole yearꎬ and the types of terpenes (19) and alkanes (18) were more
abundant than those of other compoundsꎻ The relative contents of 32 types of VOCs had significant differences (P<0.05)
among different seasonsꎻ The number of types in March was the most abundantꎬ and the relative contents of terpenes
