Chemical investigation of an extract of the marine sponge Phyllospongia papyracea , collected from the South China Sea, led to the isolation and identification of three new scalarane‐type sesterterpenoids, compounds 1 – 3 . Their structures were elucidated by spectroscopic methods, including 1D‐ and 2D‐NMR as well as high‐resolution ESI‐MS experiments. (12 α ,16 β )‐12‐Acetoxy‐16‐hydroxy‐20,24‐dimethyl‐25‐norscalar‐17‐en‐24‐one ( 1 ) was cytotoxic against the leukemia P388 cancer cell line, with an IC 50 value of 5 μg/ml.
