| Abstract: | A series of carotenoid pyropheophorbide A esters, fucoxanthin pyropheophorbide A ester (1), halocynthiaxanthin 3′-acetate pyropheophorbide A ester (2), lutein pyropheophorbide A esters (3) and (4), and mutatoxanthin pyropheophorbide A ester (5), were isolated from the viscera of the abalone Haliotis diversicolor aquatilis. These structures were determined based on UV-vis, MS, and NMR spectroscopic data. |
