Comparison of antioxidant role of methanol, acetone and water extracts of Andrographis paniculata Nees

Antioxidant properties of plants can help thwart a plethora of conditions including cancer, bronchitis, asthma, ulcers, coronary heart diseases, scabies, insomnia, senile debility, diabetes, dysentery, etc. In this study, Andrographis paniculata (Family: Acanthaceae) was investigated for antioxidant activity. 1, 1-Diphenyl-2-picryl hydrazyl (DPPH), reducing power assay, total antioxidant capacity, 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), nitric oxide test, total phenolic and flavonoid from methanol, acetone, and water extracts were investigated employing various established in-vitro system. The results divulged that methanol extract had significant activity in quenching of DPPH, reducing power, ABTS, nitric oxide, antioxidant capacity when compared to other extracts. All extracts were correlated with two specific standard antioxidants ascorbic acid and butylated hydroxyanisole. The methanol extract at 500 µg/ml showed the highest…
