The root of Ruellia tuberosa has exhibited significantly anti-oxidant activity when tested with different in vitro assay.
The ethyl acetate fraction of methanol extract (EAFME) showed better activity than Water extract and methanol extract of root. Also, amounts of both total phenolic and total flavonoid contents of EAFME were higher than methanol extract and water extract of root.
The methanol extract and ethyl acetate fraction of methanol extract were showed significantly anti-oxidant activity.
