Abstract

Aim: Evaluation of effect of shodhana process of datura seed (Datura stramonium) antioxidant activity. Methods: The datura was purified with two different processes viz. cow’s urine, and cow’s milk by Dolayantra method. Antioxidant activity was evaluated by in-vitro 1,1-Diphenyl-2-picryl hydrazyl (DPPH) radicals scavenging activity and Ferric reducing power ability (FRPA) assay. Result: cow urine purified datura (CUD) showed a significant effect in inhibiting DPPH, reaching up to 85.96% at concentration 1000 mcg/ml and its IC50 was 314.3 mcg/ml while Unpurified Datura Seed (UD) reaching up to 86.06% at concentration 1000 mcg/ml and its IC50 was 171.73 mcg/ml. The Cow Milk Purified Datura Seed (CMD) extract reach 69.72% at concentration 1000 mcg/ml and its IC50 value was 640. The IC50 value of Ascorbic acid was 23.35 mcg/ml. CUD showed a significant effect in reduction of ferric ion, reaching up to 85.59% reduction at concentration 1000 mcg/ml and its EC50 was 304.46 mcg/ml while UD reaching up to 86.11% at concentration 1000 mcg/ml and its EC50 was 280.28 mcg/ml. CMD extract reach 52.28% at concentration 1000 mcg/ml and its EC50 value was 1091.3mcg/ml.
