Astaxanthin, a naturally occurring carotenoid pigment possessing strong antioxidant property has been detected to play a vital role in the protection against lipid peroxidation and oxidative damage of LDL cholesterol, cell membrane, cells and tissues. It is available from several biological sources particularly the microalgal species Haematococcus pluvialis, but the salt tolerant mangrove vegetation present in the deltaic lobe of Indian Sundarbans has been documented as one of the most potential sources of astaxanthin. This paper documents the accumulation of astaxanthin in six species of mangroves (Avicennia officinalis, Avicennia alba, Avicennia marina, Sonneratia apetala, Aegiceros corniculatum and Bruguiera gymnorrhiza) at ten different stations having different environmental conditions in the Hooghly-Matla estuarine complex of Indian Sundarbans. Although these six species share the same brackish water media, but significant variation in the leaf astaxanthin level confirms the concept of species-specificity and effects of various physico-chemical variables on mangrove astaxanthin.
