Edible greens, especially wild greens, play an important role in traditional diets and are rich in polyphenols and other compounds. The polyphenols represent a large group of at least 10,000 different compounds that contain one or more aromatic rings with one or more hydroxyl groups attached to them. They have been known to exhibit antioxidant properties in vitro, and they also play a major role to prevent chronic degenerative diseases caused by using synthetic antioxidants or the presence of free radicals in the body. The present paper aimed to extract and analyze the total polyphenol content, total flavonoid content, and the antioxidant activity in Cynodon dactylon, Hibiscus sabdariffa, Allium fistulosum using soxhlet and ultrasound methods of extraction with solvents ethanol and distilled water and compare their efficiency. The total phenolic content (TPC) and flavonoid content (TFC) was determined by established methods. The In vitro antioxidant activity of the extract was performed by 2,2-diphenyl-1-picrylhydrazyl radical scavenging method. It was observed that plant parts of C.dactylon, have high antioxidant activity with a value of 81.071 when compared to the values, 35.357 and 13.857 of A.fistulosum and H.sabdarifa respectively.
