Abstract
Two novel sesterterpenoids, 12 alpha-acetoxy-19 beta-hydroxyscalara-15 ,17-dien-20,19-olide (3) and 12 alpha,-16 beta-diacetoxyscalarolbuteno lide (5), and a new 9,11-secosterol, 3 beta-hydroxy-5 alpha,6 alpha-ep oxy-9-oxo-9,11-seco-5 alpha-cholest-7-en-11-al (6), were isolated from the marine sponge Spongia matamata from Palau together with the known compounds scalarin (1) and 12 alpha-acetoxy-16 beta-hydroxyscalarolbu tenolide (4). The structures were determined by interpretation of spec troscopic data.
