The present study aims to make an evaluation of some secondary metabolites and determination of the antioxidant potential of P. aquilinum plant extracts obtained by means of a simple and rapid TLC method. The latter revealed the presence of terpenes, sterols, steroids, flavonoids, polyphenols, saponins, sugars and amino acids. The evaluation of the potential antioxidant was assessed on phenolic and flavonoid compounds. These compounds’ dosages revealed different levels, but the highest antioxidant activity was found in the hydro-ethanol extract followed by the aqueous extract. Among the two families of evaluated antioxidants, phenolic compounds were found to be higher in the hydro-ethanolic extract (75.18 mgEAG/gM_S), followed by the aqueous extract (66.78 mgEAG/gM_S) and lower in the ethanolic extract (12.39 mgEAG/gM_S). Whereas flavonoids, less significantly elevated, showed values of 2.58 mgECa/gM_S for the hydro-ethanolic extract, 2.24 mgECa/gM_S for the aqueous extract and 1.58 mgECa/gM_S for the ethanolic extract. However, the antiradical activity was also evaluated. Contrary to the antioxidant activity, the most important antiradical activity was observed on the hydroethanolic extract with a rate of 3.61 mg/mL, then a weak activity on the aqueous and ethanolic extracts respectively 6.18 mg/mL and 15.81 mg/mL, then less important on the aqueous and hydro-ethanolic extracts respectively at levels of 6.18 mg/mL and 3.61 mg/mL.
