Presence of benzoate-type toxins in Gymnodinium catenatum Graham isolated from the Mexican Pacific

Benzoate type toxins have been described as an important component of Gymnodinium catenatum cells. In this paper we study these toxins in a G. catenatum strain isolated from the Mexican coast. A partition of the toxins was done by solid-phase extraction on a COOH cartridge and detected by HPLC coupl...
