title: Sesquiterpene quinols/quinones from the Micronesian sponge Petrosaspongia metachromia.
abstract: Two new sesquiterpenes, pelorol (1) and 5-epi-smenospongine (2), and seven known ones (3-9) were isolated from the sponge Petrosaspongia metachromia, collected from Yap, Federated States of Micronesia. Their structures were determined from spectral data. Pelorol (1) possesses a new carbon skeleton.
