OBJECTIVE
Atriplex lentiformis (Torr.) S.Wats (Chenopodiaceae) is a wild plant which is in use by Bedouin in treatment of general fatigue, therefore, there is a need to explore the potential antioxidant activity of the extracts and isolated compounds of this plant.
METHODS
Column chromatography and

Vesicular trichomes play a key role in excluding toxic ions from some halophyte species, preventing the essential processes and functions of plants from being altered. Thus, the present study aimed to evaluate the influence of these structures on Atriplex nummularia irrigated using waters with three
