Our results showed that A. boeticus was superior to the other 3 species in all the conducted tests. In fact, it had the highest polyphenolic content. In addition, its aqueous extract showed the highest antibacterial activity, while the methanolic extract showed the highest antifungal and antioxidant activities. Further studies are needed to identify and characterize these constituents.
