Abstract
Die Messung der PSP-Belastung (paralytic shellfish poisoning) von Schalentieren erfolgt vor allem mit Hilfe des Maus-Biotestes. Um PSP-Toxine sowohl qualitativ als auch quantitativ besser bestimmen zu können, wurden chromatographische Verfahren mit Fluorescenzdetektion entwickelt. Diese HPLC-Methoden sowie die Kopplung HPLC/MS gelangten zum Einsatz, um in spanischen Muschelkonserven ein neben Saxitoxin vermutetes zweites PSP-Toxin nachzuweisen. Es zeigte sich, daß in den 1986 in der Bundesrepublik Deutschland wegen zu hoher PSP-Konzentrationen beanstandeten Muschelkonserven vor allem Decarbamoyl-Saxitoxin enthalten war. Levels of paralytic shellfish poisoning (PSP) toxins in shellfish are routinely determined by mouse bioassay: In order to improve the qualitative and quantitative determination of PSP toxins, Chromatographic techniques with fluorescence detection have been developed. These HPLC methods and the HPLC/MS coupling were used to determine a second PSP toxin which was found, in addition to saxitoxin, in canned Spanish mussels. These canned mussels were rejected in 1986 by the German food control because PSP concentrations were too high. It has been shown that these samples contained mainly dc-saxitoxin.This publication has 17 references indexed in Scilit:
