Popis: An unidentified ascidian from the Arabian Sea contained nine new alkaloids of the lamellarin class together with lamellarin N. The structures of the 20-sulfate derivatives of lamellarins T, U, V, and Y ( 1–4 ) and lamellarins T - X ( 5–9 ) were identified by interpretation of spectroscopic data. This is the first report of lamellarin sulfates.
