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.
