Abstract: Paralytic shellfish poison(PSP) composition of three species of toxic bivalves collected in Ibaraki was investigated by the HPLC analyzer for PSP from 1993 through 1996.  Their PSP was composed of protogonyautoxin-1,2(PX1,2 ; epi-GTX8, GTX8; C1,2) and gonyautoxin(GTX)-1,2,3,4  as major components.  Although the toxification of the bivalves occurred at almost the same time and geographical area during four years, some species-specific discrepancies in toxin profiles were recognized in mole ratio of N1-H arbamate toxin(GTX2,3) to N1-OH carbamate toxin(GTX1,4), which is distinguished in each part of the surf clam specimens.  The composition of PSP ingested in the bivalves was gradually changed, resulting in increase of ratio of α-epimer(GTX1) to β-epimer(GTX4) to near the equilibrium point, with slight increase of ratio of GTX2(α) to GTX3(β).
