Medical and aromatic plants have been used for centuries to provide food, condiments, medicine and healing. Walnut (Juglans Regia L.) leaf is a widely used folk medicine. Walnut is an important food for economy and culture of Turkey. Like other nuts, walnuts have become an important part of the daily diet since the time of the barn of mankind thanks to its long-term storage ability. As a result of studies on plants, it has been shown that plants may have an antimicrobial effect on their extraction with different solvents. In our study, it was aimed to investigate the antimicrobial and antioxidant activities of walnut leaf extracts's essential oils in Corum province and its vicinity. The walnut leaf extracts were weighed and extracted with 200 ml of solvent in a Soxhlet apparatus. The extracts were extracted with ethanol at 60-80 °C and chloroform at 45-65 °C for 8 hours. Disc diffusion method was applied to antimicrobial activity on S.aureus ATCC25923, C.albicans ATCC10231, E.coli ATCC25922 and E.faecalis ATCC29212 strains. The Total Antioxidant Status (TAS) of the samples was determined spectrophotometrically by the method of Erel. In ethanol extracts, the maximum inhibitory zone was determined against C.albicans (18.5±1.5mm) followed by E. faecalis (13.0±1.0mm), S.aureus (10.0±0.5mm) and E.coli(4.5±1.5mm). In chloroform extracts, the maximum inhibitory zone was determined against C.albicans(16.05±0.5mm) followed by E.faecalis (10.0±1.5mm), S.aureus(8.0±1.0mm) and E.coli(2.5±1.0mm). In conclusion, all microorganisms used in this study were found to have various degrees of zone. TAS level was found higher in ethanol extract than in chloroform extract. [ABSTRACT FROM AUTHOR] |
