Abstract
A highly branched isoprenoid (HBI) diene found in Antarctic sea-ice diatoms and surface layer (0-2 cm) sediments from Antarctica is identified as 2,10 ,14-trimethyl-6-methylene-7-(3'-methylpent-1-enyl)pentadecane. The identifi cation was made by comparison of GC-MS mass spectra and retention indices o n both polar and apolar GC stationary phases with those of the diene authen ticated by NMR after isolation from a laboratory culture of the diatom, Has lea ostrearia.
