Eugenia mooniana Wight. Is a aromatic plant with restricted distribution and native to India and Sri Lanka. The present work reports the volatile chemical composition of E. mooniana leaves and their antimicrobial activity against standard strain. The leaf essential oil was isolated by hydrodistillation method (oil yield 0.2%v/w), and analysed by GC-MS (Shimadzu Nexis GC 2030). Fourty four compounds were identified from the oil. The major class of compounds were sesquiterpenoids followed by monoterpenoids. Major compounds identified in the leaf oil were the monoterpenoids myrcene (2.8-%), β-ocimene (9.9%), and sesquiterpenoids caryophyllene (5.5%), δ-cadinene (12.1%), epi α-cadinol (7.5 %) and α-cadinol (12.9%). The antimicrobial activity oil was tested against bacteria and fungus strain by agar well diffusion method. The oil showed inhibitory activity against fungus Candida albicans and gram negative bacteria Proteus vulgaris, Salmonella typhii, Staphylococcus aureus and Vibrio fluvialis.
