Abstract

Lippia citriodora H. B. K. was imported in Iran for food and medical industry. In this research due to Essential Oil composition and Antifungal activity, the aerial parts of plant in before and after flowering satages were collected from the field in Khuzestan in June 2011. The Essential oils were obtained by hydro distillation (Clevenger apparatus) and were analyzed by (GC) and (GC-MS). To measure antimicrobial activity, the methanolic extracts of these organs were prepared by percolation method and antimicrobial activity were measured against four gram-positive and negative strains of bacteriaand two fungi starins by disk diffusion method in inhibition zone diameter. Results were showed that the Geraniol (35. 78%) and zingiberene (19. 9%) were the main compounds of Essential Oil in before flowering, althought the Davanone (36. 4%) and p-cymene (16. 5%) were predominant components in after flowering stage. The tested fungi and gram-positive bacteria were showed higher sensitivity to the concentrations of plant extracts than gram-negative bacteria. In addition, the antimicrobial effects increased with increasing concentrations of the extracts. There was no significant difference between the degree of antimicrobial activity of vegetative and reproductive extracts.
