Resumo:

A method based on protein phosphatase enzyme activity inhibition for the detection of diarrhetic shellfish poison (DSP) was used to analyze the DSP toxicity in three oyster samples. Based on the standard dose-effect curve developed with a series of okadaic acid (OA) standard solutions, the DSP toxicity of the three oyster samples collected were screened, and the results showed that there were no OA and dinophysis toxins ( DTXs) in the samples without hydrolization. However, the OA toxicity could be detected in two of the hydrolyzed samples, and the OA toxicity of the two samples were 1.81 and 1.21 mu g OA eq./kg oyster, respectively.
