The ethanol extract from aerial parts of Ranunculus were investigated for its chemical composition by LC-ESI-MS/MS technique, which allowed to identify a series of glycosylated flavonoids and one phenolic acid. RBEE extract showed acetyl-cholinesterase inhibition higher than the reference compound Galantamine at a concentrationof 200 µg/mL. A moderate antibacterial activity of the extract was also obtained against Staphylococcus aureus ATCC43300, Citrobacter freundii ATCC8090, and Proteus vulgaris ATCC29905 at a concentration 100 µg. Additionally, a good reduction in plasma coagulation time at 200 μL was also observed for RBEE.
