Abstract

Aim: The present study is focused on phytochemical analysis and different biological activities of leaf and floral parts essential oil of Corymbia citriodora.

Methodology: GC/MS analysis was conducted using HP-5MS column. DPPH free radical scavenging, reducing power assay were used for evaluating the antioxidant activity, protein denaturation, protease inhibitory assay for anti-inflammatory, Allium cepa assay for cytotoxicity analysis and Vigna radiata germination assay for herbicidal activity.

Results: GC/MS analysis revealed α-pinene, citronellal, o-cymene, 10-epi-eudesmol, α-eudesmol as the major compounds in the floral part essential oil while citronellal, citronellyl acetate, trans-caryophyllene, were the major compounds in the leaf essential oil. Essential oils showed the highest antibacterial activity towards Staphylococcus aureus and Bacillus subtilis at 500 μg ml-1 and antifungal activity against Aspergillus fumigatus and Saccharomyces  cerevisiae at 500 μg ml-1. Allium cepa assay revealed that both the essential oils possessed negligible mutagenic effects. The essential oils showed both antioxidant and anti-inflammatory activities. C. citriodora leaf essential oil showed herbicidal effects of the essential oils.      

Interpretation: The present study showed that both leaf and floral part essential oil of C. citriodora can be utilize in different industrial prospectives .      

Key words: Anti-inflammatory, anti-microbial, Corymbia citriodora, Essential oil
