Abstract

Antioxidants are able to either delay and inhibit the oxidation processes which take place under the influence of atmospheric oxygen or reactive oxygen species. Hence, the study was aimed to understand the antioxidant capacity of aqueous extract of dry Ceiba seeds. The dry Ceiba seeds purchased was ground to a powder and then aqueous extract was prepared by taking 25, 50, 75, 100mg concentration. Each concentration was assessed for secondary metabolites and antioxidant activities. The Ceiba seeds was found to contain higher flavonoid (194.66±4.61mg/g) and phenolics (176.0±8.00mg/g) in moderate amount. Presence of these phytochemicals add antioxidant property to it. Here in our study, nitric oxide scavenging, reducing power activity was effective when compared to other antioxidant activities.
