The charge (relative concentration) of antioxidants in aqueous extract and dehydroleucodine (DhL) from Artemisia douglasiana Besser was determined employing a procedure based on the quenching of luminol-enhanced chemiluminescence. Total reactive antioxidant potential (TRAP) and total antioxidant reactivity (TAR) values were determined. The data reported in the present work indicate that the extract of Artemisia douglasiana Besser and DhL showed antioxidant capacity. This activity is more pronounced in the extract, suggesting the presence of several antioxidants in Artemisia douglasiana
