Comparative antisickling and antioxidant activities of cultivars in relation to their metabolite profiling using LC/MS.

is native to South America and is cultivated worldwide mostly for its medicinal benefits. The plant is used traditionally in respiratory disorders such as dry cough, in the treatment of fever and stomach pain, and as an antimicrobial and analgesic. The antisickling and antioxidant effects of the flowers of (Kunth) Dugand (red) and cultivar alba (white) were compared using an assay in 2% sodium metabisulfite sickling induction model, DPPH, and metal chelation assays.
