description: Natural antioxidants, particularly in fruits and vegetables have gained increasing interest among consumers and the scientific community because epidemiological studies have indicated that frequent consumption of natural antioxidants is associated with a lower risk of cardiovascular disease and cancer (3). The contents of phenolic compounds and their antioxidant activity in selected grass species have been poorly investigated. [...]testing their antiradical properties is of interest, primarily in order to find new sources of natural antioxidants (4). 1 ml sample of different concentration were taken. 1ml 0.2M sodium phosphate buffer pH 6.6 was added to each sample. 1ml of 1% potassium ferricyanide was added and incubated at 500C for 20 mins. 1ml of 10% TCA (W/V) was added and then the samples were centrifuged at 2000 rpm for 10 mins, 2.5ml of upper layer was taken and mixed with 2.5 ml DW. 0.5 ml of 0.1% fresh ferric chloride was added and then the readings for their optical density were taken at 700 nm. [...]the natural antibiotics in the form of phenols and flavonoids can be easily extracted and thus it offers opportunities to formulate value added products in nutraceutical and food applications to enhance health benefits.
