Antioxidant and anti-inflammatory activities of the flower extracts of Argemone mexicana L.

Abstract

To assess the antioxidant and anti-inflammatory activities of the powder sample derived from the ethyl acetate fraction of the floral Argemone mexicana L. For antioxidant efficiency, the floral extract was evaluated using 1, 1–diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging assay and the FRC (Ferric Reduction Capacity) assay. In vitro anti-inflammatory activity was assessed using human peripheral blood mononuclear cells (PBMC) induced by lipopolysac-charide (LPS) and the production method of nitric oxide (NO). The powder sample extracted from ethyl acetate fraction of the floral of Argemone Mexicana L showed good antioxidant activity with the comparative standard sample in scavenging DPPH radicals and in FRC assay. In the cell viability (PBMC influenced by LPS) method and the Nitric oxide (NO) assay, this sample showed even able anti-inflammative activities. Such results indicate a significant antioxidant and anti-inflammatory activity in the powder sample obtained from ethyl acetate fraction in the flower of Argemone mexicana L.
