Chondria crassicaulis

The dimethylarsinoyl derivative of sulfated ribitol (see Fig. 2, compound 15) was isolated from the red alga Chondria crassicaulis (38). It had been observed as a major arsenical in C. crassicaulis by high performance liquid chroma-tography-inductively coupled plasma mass spectrometry (HPLC-ICPMS), and was initially reported as an unknown because it did not match any available standard (39). Subsequently, the compound was isolated and a chemical structure was proposed chiefly on nuclear magnetic resonance (NMR) data chemical synthesis of authentic material confirmed the proposed structure (38).
