The antimicrobial activity of infusion, decoction, ethanol extract and fractions obtained by successive extraction of Viola tricolor herb with dichloromethane, ethyl acetate and methanol was evaluated. The infusion, decoction and ethanol extract were found to be most effective against the tested
Inhibitory potential of the dichloromethane, ethyl acetate, ethanol, and aqueous extracts of Viola odorata L. (VO) was investigated against tyrosinase (TYR) and cholinesterases by microplate assays. The antioxidant activity was tested using six in vitro assays. Only the ethanol extract inhibited TYR
A fractionation protocol for the isolation of a highly purified polypeptide fraction from plant biomass is described. The procedure dereplicates ubiquitous substance classes known to interfere with bioassays often used in natural product-based drug discovery programs. The protocol involves
