Abstract: Two new scalarane-type sesterterpenes namely phyllofolactones H(1),I(2)have been isolated from the sponge Phyllospongia sp.collected in the South China Sea.The structures of these compounds were elucidated by interpretation of spectra data.The new sesterterpenes possess α,β-unsaturated γ-lactone moieties and have hydroxyl groups attaching the C-12 and C-16.
