dc.description.abstractTerthiophenes were obtained from hexane (DPH) and acetone (DPA) extracts, and flavonoids from DPA and methanol (DPM) extracts. The interaction with Cu2+ of extracts and isolated compounds of Dyssodia pinnata showed two effects in EPR: reduction and chelation; flavonoids exhibited both effects, while terthiophenes showed only reduction. DPA, DPM, and flavonoids were active in DPPH and TBARS assays. Quercetagetin‐7‐O‐β‐glucoside showed the highest antioxidant and chelating activities, 3‐glycosidated flavonoids were less active. Upon irradiation extracts and terthiophenes induced 1O2 formation.es_MX
