4 pages, 1 figure, 1 table. Pantoneurotriols 1a and 2a are acyclic polyoxygenated monoterpenes isolated from the Antarctic endemism Pantoneura plocamioides together with compounds 3 and 4. The stereochemistries of these compounds were established by spectroscopic methods and pantoneurotriols have been proposed as biogenetic precursors of pantofuranoids, uncommon monoterpenes isolated from the same species. It was interesting to find compounds 4 and 5, metabolites first isolated from Plocamium cartilagineum, in a species belonging to a different order such as P. plocamioides.
