Abstract:

The volatile oils of endophytic fungus A14 (Aspergillus sp.) from Aquilaria sinensis were extracted by solvent method and their antimicrobial activities against 3 pathogens were tested by agar disc diffusion method. The results indicated that the volatile oils of A14 exhibited weak antimicrobial activities against Staphylococcus aureus, Methicillin-resistant S. aureus (MRSA) as well as Candida albicans. Fourteen ingredients were identified from the volatile oil of A14 by GC-MS analysis, and mellein was the main component, which accounted for 93.41% of the peak area.

Key words: Aquilaria sinensis (Lour.) Gilg, Aspergillus, Endophytic fungus, Volatile oil, Antimicrobial activities, GC-MS
