Comparison of antioxidant activities of novel peptides isolated from Azadirachta indica and Selaginella bryopteris

Abstract

Aim: The aim of this study was to compare the antioxidant activities of novel peptides isolated from Azadirachta
indica and Selaginella bryopteris. Material and Methods: The novel peptides were isolated from the young
leaves of A. indica and the fronds of S. bryopteris using inexpensive paper chromatography technique. The
isolated peptides were studied for in vitro antioxidant activities. Results and Discussion: In vitro antioxidant
studies showed that both the peptides are free radical scavengers and the radical scavenging activity increases
with increase in concentration of the peptides. Conclusion: The peptide isolated from the fronds of S. bryopteris
showed more free radical scavenging activity when compared with the peptide isolated from the young leaves of
A. indica.
