抄録: This investigation was carried out in order to demonstrate the occurrence of carbonund (2-AEP) in the sixteen species of edible shellfishs. Edible shellfishs had previously been shown to contain of 2-AEP , the present study has added a number of new edible shellfishs to the positive list. 2-AEP has been found large amount in chloroform-methanol soluble (lipid) fraction and in the TCA-insoluble fraction. About twenty-one mg, nine mg, five mg and two mg of the 2-AEP were isolated from the lipid of the TENGUNISHI, Hemifusus ternatanus, UCHIWAEBI, Ibacus ciliatus, GAZAMI, Portunus trituberculatus and UNI, Hygrosoma hoplacantha, resppectively. The compound was purified with a combination of ion exchange column chromatography with Dowex 50-X 4 and Dowex 1-X 8 resins. The infrared spectrum of the isolated compound showed an absorption band at 1180 cm-1 due to C-P bond, and was essentially identical with that of the authentic 2-AEP. Upon hrdrolysis of the compound by strong acid, neither change in the chromatographic behaviors of this compound nor liberation of inorganic phosphate was observed. The stability of the compound to acid hydrolysis suggested the presence of a C-P bond. On comparison with syntetic compound, the aqueous hydrolysis product behaved like 2-aminoethylphosphonic acid on thin layer chromatogram. It has been demonstrated that the sixteen species of edible shellfish used here contains high concentration of the 2-AEP.
