Evaluation of antioxidant activity of large cardamom (leaves of Amomum subulatum)

Amomum subulatum, is commonly used spice. In the present study the ethanolic and aqueous extracts of leaves of Amomum subulatum is evaluated for antioxidant activity by the 1,1Diphenyl -2-picrylhydrazyle (DPPH) free radical scavenging activity, :-carotene bleaching assay and total phenolic contents methods. The ethanolic extract showed significant antioxidant activity. The IC50 of ethanolic extract, total phenolic content, and mean antioxidant activity are 8.25±2.0 μg/ml, 11.04±0.2, 41.2±1.5% respectively and that of ascorbic acid was 2.0±0.14 μg/ml whereas BHA was found to be 50.3±0.6. The study showed that the ethanolic extract consumption could exert beneficial effects due to its antioxidant activity.
