Several water-soluble pigments were purified from gametangia of Bryopsis maxima by liquid chromatography and characterized by pyridylamination and high-performance anion-exchange chromatography. The structure of the main red pigment is proposed based on the data of infrared spectrum, Mass spectrum, 1H and 13C NMR spectra and pyridylamino analysis. As a consequence, this pigment contained a tetrapyrrole with phytol and a sugar chain comprised of xylose and glucose. The sequence of the sugars in the chain was determined based on its Mass spectrum. The pigment was similar to chlorophyll-origin pigments observed in other plants. No aldehyde group, however, was present at C5 in the open tetrapyrrole chain
