摘　　要：利用动态顶端采集和GC–MS系统,分析了绿萝和常春藤挥发性有机物的组分,其中绿萝鉴定出挥发性成分23种,常春藤30种。初步判定绿萝的萜烯类化合物有11种,占挥发物总量的64.73%,以α–蒎烯和莰烯含量最高,分别占30.67%和14.92%;常春藤的萜烯类化合物有13种,占挥发物总量的61.41%,也以α–蒎烯和莰烯含量为高,分别占28.98%和14.70%。利用α–蒎烯、莰烯和桉树脑单体对枝孢霉、附球菌、链格孢、青霉和黑曲霉进行了抑菌活性的测定,结果表明这3种挥发物单体在50μL·mL-1浓度时对5种真菌的抑菌率均达100%;在10μL·mL-1浓度时对黑曲霉的抑菌率分别为92%、85%和23%;在5μL·mL-1浓度时,对青霉的抑菌率分别为60%、25%和74%。综合抑菌力的强弱为α–蒎烯>桉树脑>莰烯。The volatile constituents of bunting（Scindapsus aureum）and Chinese ivy（Hedera nepalensis var.sinensis）were analysed by dynamic headspace-GC-MS analysis.Twenty-three volatile compounds were preliminary determined including 11 terpene compounds accounting for 64.73%（α-pinene and camphene were accounted for 30.67% and 14.92% respectively）in bunting.Thirty volatile compounds were preliminary determined including 13 terpene compounds accounting for 61.41%（α-pinene and camphene were accounted for 28.98% and 14.70% respectively）in Chinese ivy.The inhibitory effect of α-pinene,camphene and eucalyptole against Penicillium sp.,Aspergillus niger,Cladosporium sp.,Epicoccum sp.and Alternaria sp.were detected.The results showed that the inhibition rates were all 100% at 3 terpene monomers concentration of 50 μL · mL-1.The inhibition rates were 92%,85% and 23% at the concentration of 10 μL · mL-1 respectively,against Aspergillus niger,and were 60%,25% and 74% at the concentration of 5 μL · mL-1 respectively,against Penicillium sp.The bacteriostatic effect,α-pinene was the best,eucalyptole was second and camphene was the worst in generally.
