Abstract

Astaxanthin extracted from Red Crab Charybdis edwardsii was assayed for antioxidant activity viz., total antioxidant, reducing power, hydrogen peroxide radical scavenging assay, and DPPH free radicals scavenging activity. Final concentration of astaxanthin was quantified to be 49.05 µgg using the standard astaxanthin. The antioxidant activity was found to be 60%, hydrogen peroxide scavenging activity showed 89% inhibition, whereas 1,1-diphenyl-2-picrylhydrazl (DPPH) activity showed 86% of scavenging activity. Present investigation proves that the astaxanthin from C. edwardsii acts as a promising antioxidant source, which can be used in food, pharmacological and aquaculture sectors Anandakumar Arunkumar | Gnanakkan Ananthan | Rajaram Murugan"Antioxidant Activity of astaxanthin isolated from Charybdis Edwardsii (Leene and Buitendijk ,1949) from Pazhayar, Southeast Coast of India" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-2 | Issue-5 , August 2018, URL: http://www.ijtsrd.com/papers/ijtsrd15762.pdf http://www.ijtsrd.com/biological-science/animal-science/15762/antioxidant-activity-of-astaxanthin-isolated-from-charybdis-edwardsii-leene-and-buitendijk-1949-from-pazhayar-southeast-coast-of-india/anandakumar-arunkumar
