Abstract
Two new water soluble 320 nm UV-absorbing compounds, sulfate esters of two imino mycosporines, were isolated from methanol extracts of a ree f-building coral and purified by HPLC. Structural elucidation yielded the molecular formulae C12H19N2O9S (5) and C11H17N2O9S (6). These have been given the trivial names Palythine-Thr sulfate and Palythine-Ser- sulfate respectively.
