This research aimed to determine the content of different tocopherol levels in muscle and ocular cavity of matrinxã fishes captured in the Central Amazon Region - Brazil. For the antioxidants determination, three batches, each consisting of 5 fish, during two different seasons. The analyses were performed according to the AOCS Ce 8-89 (1993) methodology in chromatography HPLC PERKIN ELMER - Isocratic LC 250 pump couple to fluorescence detector (SHIMADZU - RF - 10AxL). The a-tocopherol was predominant in the different seasons. The tocopherol content ranged from 0.43 to 0.04mg 100-1 and from 8.2 to 0.06mg 100g-1 in the muscle of matrinxã captured in the flood ad dry season, respectively. The tocopherol content in the adipose tissue of the orbital cavity of matrinxã captured in the flood ad dry season showed ranged from 0.09 a 0.02mg 100g-1 and from 0.42 to 0.03mg 100g-1, respectively.
