Determination of Antimicrobial, Antioxidant and Antibiofilm Activity of Some Alyssum L. Species in Anatolian Flora

Abstract

The Alyssum L. genus which is spread in the Eastern Mediterranean is known by the public as 'Rabid weed' or `Kevke'. Many of these species are seen as a way to prevent disasters such as erosion, both due to drought resistance and low soil selectivity. Also Alyssum known as 'Tooth weed', it has been used to reduce tooth sore, bladder stones and spasm. In this study, in order to examine antibacterial and antifungal activities, extracts obtained from three naturally growing plants ( Alyssum caricum T.R.Dudley and Hub.-Mor., Alyssum discolor T.R.Dudley and Hub.(-)Mor. and Alyssum sibiricum Willd.) in Turkey were examined on seventeen bacteria and two fungal strains by disc diffusion method. In addition, antimicrobial activity was supported by the Minimum Inhibition Concentration (MIC) and Minimum Bactericidal Concentration (MBC) method. DPPH (2,2-diphenyl-1-picrilhydrazyl) method was used to investigate the antioxidant activities of plant extracts, and crystal violet binding method was used to prevent biofilm formation. As a result, A. caricum ethanol extract showed the best effects in antimicrobial activities. None of plants were effective against fungi. A. sibiricum shows the best activity in antibiofilm activity and A. caricum was showed the best result in antioxidant activity.
