Studies on the antioxidant and analgesic activities of Aztec marigold (Tagetes erecta) flowers.

Commercially available Aztec marigold (Tagetes erecta) flower extract (Af.Cr) was evaluated for the in vitro antioxidant activity and in vivo analgesic effect on acetic-acid-induced abdominal writhing. The results revealed the presence of pronounced antioxidant potential in Aztec marigold flowers and a dose-dependent (100 and 300 mg/kg) analgesic effect. The antioxidant and analgesic activities obtained seem to be in good accordance with the medicinal uses of Aztec marigold as an anti-inflammatory and analgesic.
