Antioxidant Activity and Determination of Gallic Acid and Quercetin in Osyris alba L. Root Extract. The Root Oil Contains Essential Fatty Acids

Osyris alba L. (Santalaceae) is a shrub that grows wildly in southern Europe, North Africa and South-west Asia. In Algeria, the decoction of the root bark of this plant has been used since ancient times in folk medicine by the local population in the region of the mountains of Béni- Snousse (South west of Tlemcen), as a fortifying, antianaemic and as an anti-inflammatory agent. The aim of this work was to evaluate the antioxidant activity of the phenolic compounds of the root by using DPPH, FRAP, TAC methods. Determination of the phenolic profile of the root extract was assessed using HPLC-DAD technique (High Performance Liquid Chromatography-Diode Array Detection). While the determination …
