The production of reactive oxygen species (ROS) might affect the normal mechanism
of mangrove plants when it is in contact with polychaetes. Mangrove plant has
antioxidants machinery which play role to scavenge the ROS. The aim of this study
was to determine and compare the non-enzymatic antioxidants activities i.e α-
tocopherol, ascorbic acid and carotenoids in leaves and roots of Rhizophora sp.,
Avicennia sp. and Sonneratia sp. in response with polychaetes distribution. Leaves and
roots of mangroves were taken from Pantai Morib, Banting, Selangor. Amount of α-
tocopherol have no significant different between leaves and roots of three different
types of mangroves. Leaves of Sonneratia sp. and roots of Rhizophora sp. were high
in ascorbic acid with (615.81 ± 214.62) μg /g fwt and (605.38 ± 73.45) μg /g fwt
respectively. The highest carotenoids content was on leaves (61.00 ± 8.43) μg /g fwt
and roots (27.55 ± 3.53) μg /g fwt of Sonneratia sp. Results indicated the nonenzymatic
antioxidants were significantly diferrent for each type of mangroves.
