Antioxidant potentialities and gastroprotective effect of Reichardia picroides extracts on Ethanol/HCl induced gastric ulcer rats.

The goal of this study was to determine for the first time the polyphenol content, antioxidant, and gastroprotective properties of the roots and leaves of Reichardia picroides. TPC considerably varied as a function of organs and solvent nature and ranged from 50 to 284.80 mg GAE/g DW. Leaves exhibited the highest amount of phenolics by using acetone 70%, the same tendency was observed for antioxidant activity. Besides, in vivo gastro-protective effects following HCl/EtOH-induced ulcer models displayed that roots extract at a high dose (500 mg) seemed to be the best performing extract with a decrease of ulceration index (UI) and an increase in the percentage of protection (PP), SOD, CAT, and GPX activities. All these data have been proved with principal component analysis (PCA). Overall, the results indicated that R. picroides could be considered a valuable source of natural compounds, which are beneficial for human health.
