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 components of the volatile organic compounds of Ipomoea vivo and Ivy were analyzed by using the dynamic apical acquisition and GC-MS system. Among them, 23 species of Volatile Oil and 30 species of Ivy were identified. The results showed that 11 kinds of terpenoids were identified, accounting for 64.73% of the total volatile compounds, accounting for 30.67% and 14.92% of the total, respectively. There were 13 kinds of terpenoids in ivy Accounting for 61.41% of the total volatiles. The contents of α-pinene and camphene were also high, accounting for 28.98% and 14.70% respectively. The antibacterial activity of Cladosporium fulvum, Streptococcus coccoidea, Penicillium sp. And Aspergillus niger were determined by using α-pinene, camphene and eucalyptus brain monomer. The results showed that the three volatile monomers were in 50μL · The inhibitory rates against Aspergillus niger were 92%, 85% and 23% respectively at the concentration of 10μL · mL-1 and 5μL · mL-1 The inhibitory rates against Penicillium were 60%, 25% and 74%, respectively. The strength of the combined bacteriostatic power is α-pinene> eucalyptol> camphene.
