title: GC/MS and HPLC/PDA characterization of essential oils and phenolic compounds from the aerial parts of common rue (<i>Ruta graveolens</i>)
abstract: Two different extraction methods were used to evaluate the medical value of common rue, Ruta graveolens L. (RGL).The results of our 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis-3ethylbenzothiazoline-6-sulphonic acid assays indicated that the antioxidant activity of RGL essential oil extract obtained through steam distillation was very low, whereas ethanol (EtOH) extracts of RGL showed higher antioxidant activity.RGL essential oil was extracted by steam distillation and characterized by GC/MS
