Water‐soluble fractions containing arsenic compounds were extracted with chloroform‐methanol (2:1) from two kinds of jellyfish, Aurelia aurita and Carybdea rastonii . After defatting, each water‐soluble fraction was subjected to analysis by HPLC‐GFAA (column: ODS 120‐T) and HPLC‐ICP MS (column: Supelcosil LC‐SCX) for arsenicals. Arsenobetaine was detected with both analytical systems as the major arsenic compound. Besides arsenobetaine, the tetra‐methylarsonium ion and arsenocholine were also detected by HPLC‐ICP MS. The major arsenical in each jellyfish purified by ion‐exchange chromatography using Dowex 50W × 8 (H + form) and Dowex 50W × 8 (pyridinium form) was confirmed to be arsenobetaine by thin‐layer chromatography.
