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
