Abstract: To clarify the functions of plant volatile organic compounds (VOCs) on bacteriostasis and air decontamination,composition and content of VOCs in leaves of four cultivars of Osmanthus fragrans: Thunbergii,Odoratus, Aurantiacus and Semperflorens were analyzed under near-natural conditions using the thermal-desorption cold trap gas chromatography/mass spectrometer technique. The airborne microorganism count (bacteria,fungi,and actinomycetes) for the four cultivars and a control of open ground were determined for March,May,July,September,and November in 2011 using natural sedimentation. Results showed that the major VOCs as follows:(Z)-acetate-3-hexen-1-ol,hexanal,octanal,nonanal,decanal,6-methyl-5-hepten-2-one,and 3-hexenol in Thunbergii;(Z)-acetate-3-hexen-1-ol,hexanal,benzaldehyde,nonanal,decanal,6-methyl-5-hepten-2-one,and nonane in Semperflorens;(Z)-acetate-3-hexen-1-ol,hexanal,octanal,nonanal,decanal,nonene,6-methyl-5-hepten-2-one,and 3-hexenol in Odoratus and Aurantiacus. Compared to a control of open ground,the Thunbergii stands for the five data collection months had significantly lower (P < 0.01) bacterial counts;the Thunbergii stands for March,July,and September had significantly lower(P < 0.01) fungal counts;and all four cultivars for the five data collection months had significantly reduced (P < 0.01) actinomycete counts. Thus,the four O. fragrans cultivars could reduce the quantity of airborne microorganisms thereby improving air quality.[Ch,3 fig. 1 tab. 18 ref.]
