Assesment of antioxidant and phenol related enzyme assays in Karanja (Derris indica)

Abstract

The study was undertaken to identify the responses of five antioxidant enzymes viz., GPOD (guaiacol peroxidase), APX (ascorbate peroxidase), CAT (catalase), SOD (superoxide dismutase), GR (glutathione reductase) and one phenol related metabolism enzyme, PPO (polyphenol oxidase) in thirty accessions of Karanja. Highest GR (248.99 μM/min/g protein) and CAT (6.22μM/min/g protein) activity was found in NAUK-10 while highest GPOD, SOD, APX and PPO activity was found in NAUK-2 (165.16 μM/min/g protein), NAUK-13 (84.01 U/g protein), NAUK-24 (255.17 μM/min/g protein) and NAUK-11 (19.06 μM/min/g protein) respectively.
