Background:
Essential oils (EOS) possess a wide range of significant properties including antiphlogistic, spasmolytic and
antinociceptive effects. In this study, we use essential oils (Eos) from
Thymus daenensis, Thymus caramanicus
and
Ziziphora
clinopodiodes
. The context and purpose of the study: this study attempts to determine the growth inhibition level of the essential oils
of three plants against Aspergillus flavus and Aspergillus parasiticus for 14 days.
Results:
The highest rate of inhibition was observed in
Thymus daenensis
in concentration above 7 µL in 100 mL of PDA medium in
which no growth was observed during 14 days.
The Main Findings:
Among the three essential oils,
T. daenensis
contains the highest level of thymol (77.62%).
Zizipora clinopodioides
contains pulegone (31.21%), menth-3-en-8-0l (23.82%), menthol (7.21%), borneol (2.25%), carvacrol (5.38%) and piperitone (5.55%).
Only a concentration of 9 µL of essential oils of
Z. clinopodioides
can prevent mycelium growth of both fungi for 7 days. Thymus
caramanicus contains carvacrol (65.52%), p-cymene (13.21%), gamma-terpinene (4.44%), thymol (4.14%) and linalool (2.63%).
Conclusion:
Although
T. caramanicus
contains 65.52%carvacrol, its inhibition growth ability does not reach 100% in all concentrations
and it is capable of inhibiting fungal growth completely (100%) at 7 and 9 µL concentrations for one day. This indicates that compound
thymol is more effective than carvacrol in prevent of growth fungi.
