The antioxidant activity of the naturaceutical extract in vitro using total phenolic contents, total flavonoids contents, DPPH radical scavenging activity, reducing power assay, and phenolic acid contents were studied. The total phenolic and flavonoids contents of naturaceutical extract were 5.46 mg/g and 2.21 mg/g, respectively. The DPPH radical scavenging activity of natraceutical extract varied from 18.77 (200 μg/ml) to 3.44 (1,000 μg/ml). The reducing power of the natraceutical extract absorbance varied from 1.07 (0.78 mg/ml) to 3.44 (12.5 mg/ml), and reducing power of extract presented a concentration‐dependent activity were increase. The highest amounts of trans ‐ferulic acid, p ‐hydroxybenzoic acid, p ‐coumaric acid, vanillin, vanillic acid, p ‐hydroxybenzaldehyde and trans ‐cinnamic acid were observed in the naturaceutical extract at the levels of 750.79, 619.75, 531.34, 222.04, 219.28, 107.40 and 89.56 μg/g, respectively. The results implied that those antioxidant effects of the naturaceutical extracts could be harnessed in the management and prevention of degenerativing diseases associated with oxidative stress.
