Peganum harmala seeds crude hydro-methanolic extract and their fractions (obtained with ethyl acetate and butan-1-ol) were analyzed and compared for their chemical profiles of alkaloids and polyphenols content. Moreover, their antioxidant, a-glucosidase, acetylcholinesterase, and butyrylcholinesterase inhibitory activities were evaluated. The butan-1-ol fraction revealed the highest total phenolic content and exhibited the highest antioxidant capacity.
