Purpose The present study was investigated to determine in-vitro antioxidant activity and total phenolic, total flavonoids, and total tannins contents of extracts of Cedrus deodara heart wood. Materials and methods Antioxidant activity of aqueous and alcoholic extract of C. deodara heart wood was evaluated against 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), 1,1-diphenyl-2-picryl hydrazyl (DPPH), and hydroxyl radical-scavenging activity models. Total flavonoids, tannins, and phenolic content of C. deodara were also determined. Results and conclusion Among both extracts, aqueous extract showed the highest total phenolic contents (23.97 μg/g of gallic acid equivalent/g of extract). In DPPH, superoxide anion, and ABTS scavenging test, the IC 50 (μg/ml) value of aqueous and alcoholic extract was 61.89, 75.79, 87.76, 121.55, 115.29, and 122.42, respectively. Hence, the above evidences suggest that C. deodara heart wood is a potential source of natural antioxidant and can be used to prevent diseases associated with free radicals.
