Abstract The astaxanthin levels in the leaves of seven dominant mangrove species, sampled from four different stations of deltaic complex of Indian Sundarbans at the apex of the Bay of Bengal (Lat 21(0) 13'-22(0) 40' N and Long 88(0) 03'-89(0) 07' E), were measured by the ultraviolet-visible spectrophotometry, during the early summer, 2007. The selected sampling stations exhibited variation with respect to changes in aquatic salinity. Relatively higher astaxanthin level was observed in the plants sampled from high saline zone which confirms the accelerated synthesis of this carotenoid pigment under stress (saline ambient medium) condition. The inundated leaves showed more astaxanthin levels relative to the leaves that were not inundated. This is again due to the stress exerted by salinity to which the inundated leaves arc exposed. The astaxanthin content of the mangrove leaves was in the order: Heritiera fomes > Avicennia alba >Avicennia marina >Avicennia officinalis > Sesuvium sp. > Sonneratia apetala > Porterasia coarctata at all the sampling stations. It points towards the species specificity of the carotenoid pigments.
