Abstract

This study investigated the differences of essential oils and methanolic extracts according to the antimicrobial properties. Methanolic extracts of lavender, clove, and pomegranate fruit peel and essential oils of them were used to determine the antimicrobial effects on Streptococcus mutans, Streptococcus salivarius, Streptococcus mitis, Staphylococcus aureus, and Staphylococcus epidermidis by disc diffusion method. The inhibition zone diameters for the methanolic extract of pomegranate fruit peel were 14.80±0.36 mm against to S. aureus, 16.80±0.56 mm against to S. epidermidis, and 7.50±0.36 mm against to S. mitis. On the contrary, the essential oil of pomegranate fruit peel had no antimicrobial effect on Streptococcus mutans, Streptococcus salivarius, Streptococcus mitis, Staphylococcus aureus, and Staphylococcus epidermidis. The methanolic extract of lavender had no antimicrobial effect against to S. aureus however the inhibition zone diameter for essential oil of lavender was 7.53±0.61 mm against to S. aureus. The inhibition zone diameter for methanolic extract of lavender was 7.70±0.26 mm against to S. epidermidis on the other hand the essential oil of lavender had no antimicrobial effect against to S. epidermidis. The inhibition zone diameter for methanolic extract of clove was 12.10±0.70 mm against to S. mutans but the essential oil of clove had no antimicrobial effect against to S. mutans. To sum up, it was indicated that there were differences between essential oils and methanolic extracts in terms of antimicrobial effects.
