Raw material “Trifolii pratense herba” originated from southern Ukraine: diagnostic microscopic features and its antioxidant activity

As a result of pharmacognostic and pharmacological studies, diagnostic signs Trifolii pratense grass collected in the phenophase active flowering area southern Ukraine were revealed. We have proposed adoption an appendix to existing monograph State Service on Medicines Drugs Control “Trifolii inflorescences”, with raw material , appropriate microscopic identification leaves stems plant. According our previously found optimal conditions for extraction medicinal plant materials (ratio solvent-plant material, time temperature extraction), selected aqueous extract (1: 5) clover yields maximum substances from 60 min 24 hours, which showed lower values TBARS (0.541 ± 0.0291 μ M / g, mean SD), gives grounds recommend use as antioxidant, compared action ascorbic acid.
