| Abstract: | Cellular damage caused by reactive oxygen
species has been implicated in several diseases and hence antioxidants have
significant importance in human health. Cold water, hot water and methanolic
extract of Pleurotus squarrosulus were
evaluated for antioxidant activity against hydroxyl radical, DPPH (1,1-Diphenyl-2-picrylhydrazyl)
radical, superoxide radical, nitric oxide (NO) scavenging, reducing power,
ferrous ion chelating ability and -carotene/linoleic acid assay. Total phenol,
flavonoid, -carotene and lycopene content were also determined. Hot water
extract showed significant antioxidant activity in all the test systems. Hydroxyl
radical scavenging activity of all the extracts has been significant compared
to positive control. Hot water extract has been found to have higher phenolic,
total flavonoid, -carotene and lycopene content than cold water and methanolic
extract of the mushroom. Results of this study showed that, hot water extract
has maximum antioxidant property and may be utilized as a promising source of
therapeutics. |
