Homogenized aliquots (100 g) of the liver (8.4 kg, 5 m̈g As g −1 ) of a tiger shark (Galeocerdo cuvier) were extracted with chloroform/methanol, and the extracts purified by countercurrent extraction (hexane/87% ethanol), silica gel column chromatography (chloroform/methanol mixtures as mobile phases), and silica gel thin‐layer chromatography (chloroform/methanol/acetic acid). The purified samples (24 mg arsenic g −1 ) gave no 31 P NMR signal, but gave 1 H and 13 C NMR signals with similarities to those of dipalmitoylphosphatidic acid and salad on and also signals indicative of the presence of methylated arsenic compounds. The sample could contain a diacyl glyceride with a methylated arsenic group.
