Abstract

Objective: The present study was carried out to evaluate antioxidative potential of
Cassia tora seeds. Method: The antioxidant activities of different concentrations of ethanol extracts
of the seeds of Cassia tora were determined by the four assay techniques i.e. DPPH radical
scavenging assay, reducing power ability, hydrogen peroxide scavenging assay and thiocyanate
method. Results: Ethanol extract of Cassia tora seed has shown effective antioxidant activity in
all assay techniques. The results obtained in the present study indicate that the seeds of Cassia
tora are a potential source of natural antioxidants.

Key words: Antioxidant activity, DPPH, Reducing power, Cassia tora.
