Abstract：In order to determine the antimicrobial activity of the volatiles from flowers Ceropegia woodii and Commelina communis,the gas samples were collected by dynamic top collection method,and analyzed by GC-MS. The results showed that, camphene ( 3. 83% and 14. 91% from the two floral species, respectively),α-pinene(5. 89% and 31. 06%),and eucalyptole(33. 80% and 0. 45%) were most abundant. The fungistatic activity of the three terpene compounds against four fungal species, Alternaria solani,Penicillium gladioli,Epicoccum nigrum and Aspergillus niger was evaluated by mycelial growth-rate method. The results showed that α-pinene, camphene and eucalyptole all had remarkable fungistatic activity against the tested fungal pathogens. The overall fungistatic activity of α-pinene was the highest, followed by eucalyptole and then camphene. The two species of flowers could be used for development of new type of plant fungicides.
