Abstract

The present study was aimed to investigate the essential oil composition and the antioxidant properties of an Algerian Cistus albidus L. from the Aures region. The essential oil was extracted by steam distillation technique and analyzed by GC-MS and GC-FID methods and the antioxidant evaluation was determined by the DPPH radical scavenging assay. Total phenol and flavonoid contents were measured using Foline-Ciocalteau and aluminium trichloride methods. The results revealed that the main compounds were respectively 15,16-dinorlabd-8(20)-en-13-one (22.3%), methacrylic acid (17.3%) and manool (12.4%). The highest antioxidant capacity was reported for ethyl acetate extract (IC50 0.445 ± 0.112 mg/mL) which had also the highest total phenol (298.8 ± 115.8 µgAGE/mg) and flavonoid contents (262.9 ± 1.6 µgRuE/mg, respectively).
