Antibacterial Effects of 13 Evergreen Shrubs and Main Volatiles in Zhengzhou City
For the antimicrobial ability of evergreen shurbs in Zhengzhou,13 typical evergreen shurbs such as Mahonia fortunei and Nandina domestica were used to determine the antimicrobial rate by the method of plate count.Decanal,benzaldehyde,β-pinene,limonene and 3-carene were selected as the main volatiles,the antimicrobial capability of volatiles was researched by taking inhibitory zone,the min-imum inhibitory concentration and minimal bactericidal concentration as determining target.The results showed that there were significant differences in the antimicrobial rate among the 13 evergreen shrubs spe-cies(P<0.05),the bacteriostatic rate of broken leaves was greater than that of whole leaves of the same quality,Nandina domestica and Pittosporum tobira against Staphylococcus aureus was the strongest,and the antimicrobial effect of Nandina domestica against Bacillus subtilis and Escherichia coli was the stron-gest.Five volatile monomers had different inhibitory effects on the tested strains,benzaldehyde had the strongest antibacterial capability,and β-pinene had the weakest.The evergreen trees with a strong anti-bacterial capability,such as Nandina domestica should be priority selection in urban greening of Zheng-zhou City.
