Evaluation of In Vitro Antioxidant Activity of the Water Extract Obtained from Dried Pine Needle (Pinus densiflora)

Antioxidant activities of water extracts obtained from dried pine needle ( ) were measured at 0, 4, 20, 100, 500, 1,000, and 1,200 ppm and compared with those of phenolic compounds of butylated hydroxyanisole, butylated hydroxytoluene, -butylhydroquinone, ferulic acid, and α-tocopherol. The activity...

Zusammenfassung:Antioxidant activities of water extracts obtained from dried pine needle ( ) were measured at 0, 4, 20, 100, 500, 1,000, and 1,200 ppm and compared with those of phenolic compounds of butylated hydroxyanisole, butylated hydroxytoluene, -butylhydroquinone, ferulic acid, and α-tocopherol. The activity was determined as the ability to scavenge 1,1-diphenyl-2-picrylhydrazyl radical and hydrogen peroxide, reductive power, and inhibition of lipid peroxidation in a linoleic acid system using the ferric thiocyanate method and thiobarbituric acid method, respectively. Pine needle water extract (PNWE) exhibited antioxidant activity in a concentration-dependent mode at the same parameters mentioned above, and a significant difference (
