Abstract: Two sesterterpenes, which belong to the scalarane class of sesterterpenes with a 20, 24-bishomo-tetracyclic skeleton, have been isolated from the South China Sea sponge Phyl-lospongia Foliascens. The structures of phyllohemiketal Aand Bwere determined as 1 and 2 on the basis of spectral data.
