Free radicals' scavenging capacity of Thymus serpyllum L. extracts depending on applied extraction conditions and extraction techniques

Polyphenols, as plant secondary metabolites, achieve strong antioxidant capacity by scavenging free radicals, chelating metals, and interacting with lipid membranes, proteins nucleic acids. The aim of the present study was examination applied extraction conditions (particle size material, solvent-to-solid ratio, solvent type, time) techniques (maceration, heat- ultrasound-assisted extractions) on radicals' Thymus serpyllum polyphenol extracts, determined in ABTS DPPH methods. According to results, smaller particle herbal drug resulted better potential. However, this effect statistically significant for extractions according assay, maceration heat-assisted assay. Furthermore, increase ratio from 10:1 30:1 extracts higher activity regardless type technique, whereas ethanol comparison aqueous extracts. In terms time achieving highest capacity, 30 min can be recommended extraction, 5 processing ultrasonic probe. neutralization there were no differences between T. obtained using different techniques, activity, have shown significantly activity. Due properties study, may used formulations food, pharmaceutical, cosmetic, chemical industries.
