摘要：

Eight new compounds were isolated from a Western Australian sponge Spongia sp., including 12-hydroxyambliofuran (5), its acetate ester 6, five new tetracyclic diterpenes 7 - 11 and the epoxyfuranosesterterpene carboxylic acid 12. Compounds 5 and 6, each isolated as a 3:1 mixture of enantiomers as determined by a modified Mosher's ester method and chiral lanthanide NMR shift studies, are rare examples of scalemic marine natural products.
