Antioxidant and antimicrobial activities of ethanol extract of Helianthemum salicifolium (Cistaceae)

Abstract

Plants have been used by humans to treat diseases. Different plant species have been very successful in treating different diseases. Helianthemum salicifolium (L.) Mill. was used as a material in our study. The plant was extracted with ethanol (EtOH) in a Soxhlet apparatus. Then, the antioxidant (TAS) and oxidant status (TOS) of the plant extract were determined using Rel Assay kits. Their antimicrobial activities were tested against standard bacteria and fungus strains by the agar dilution method. As a result of the analysis, the TAS value of plant extract was determined as 9.490±0.195, TOS value as 14.839±0.253, and OSI value as 0.157±0.005. In this context, it was seen that the plant has important antioxidant potential. In addition, the plant extract was found to be effective against test microorganisms at 25-100 μg/mL extract concentrations. Also, the extract was found to be more effective against fungus strains (C. albicans, C. Glabrata, and C. krusei). As a result, it was determined that H. salicifolium could be a natural antioxidant and antimicrobial source.
