Study of the antioxidant activity of the herb alfalfa sickle (Medicago falcata L.)

Objective: study of the antiradical and antioxidant activity water, water-alcohol alcohol extracts obtained from alfalfa sickle grass. Materials methods. As an object research activities sickle, grass in flowering stage, which was harvested Russian Federation Kursk region, considered. The evaluated using a titrimetric method based on result interaction substances reducing nature that are present potassium permanganate used as titrant. Antiradical studied by spectrophotometric ability to inactivate DPPH (2,2-diphenyl-1-picrylhydrazyl). content phenolic compounds (direct spectrophotometry) terms chlorogenic acid flavonoids (differential rutin determined. Statistical analysis process data experiments. Results. Processing results during experiments determine level for various concentrations aqueous, extractants confirmed presence such effects all types studied. Under experimental conditions with use 30% ethanol extractant, maximum atioxidant observed at 58.55%. 96% extractant showed similarly activity, 56.63%, is slightly less, but significantly exceeds other indicators. fixed (0.51%) when ethanol. same conditions, were recorded index 0.88%. visualize direct correlation between herb Medicago falcata L. it. then this extraction hydroxycinnamic acids less (0.14% 0.04% respectively). Conclusion. resulting series collected phase confirm prospects medicinal plant raw materials material having makes it possible consider basis continuing pharmacological research.
