Abstract

The marine brown alga, Dictyota volubilis, was found to contain four unusually substituted hydroazulenoid diterpenes (1 - 4) as well as the known compounds dictyol G acetate (5) and dilophol. The structures of all isolates were secured by detailed analysis of their spectroscopic data; IR, MS, and NMR.

Key words
