In vitro anti-oxidant activity of various solvent fractions of Cassia fistula L. pods

Abstract

Cassia fistula L. is a common medicinal plant has been used for the treatment of various ailments such as convulsion, inflammation, pain, infectious diseases etc. The Present study was aimed to estimate the total phenolic and flavonoid content and to examine the antioxidant activity of such as n-hexane (NHF), ethyl acetate (EAF) and aqueous fractions (AQF) of Cassia fistula L. pods. The antioxidant activity was assessed by superoxide scavenging and reducing power abilities. The antioxidant potency was found to be decreasing order of EAF, NHF and AQF and had good co-relation with their polyphenolic and flavonoid content. This study shows that Cassia fistula L pods can serve as a good source of antioxidants and thus used for preventing oxidative stress related disorders.
