المستخلص : The characteriszation of the non-protein constituents of two species of tire corals Millepora dicholoma and Miliepora plaryphylla, exhibits very interesting results. The compounds were identified by gas chromatography-mass spec¬trometry (GCMS) and nuclear magnetic resonance (NMR) spectroscopy. The solvent extracl\i of !he two species revealed four Wall esters. The compounds were identified as CJQ."""P" C""""O,, C}fH""O, and C,.H",O, respectively. The presence of these compounds has been reported previously in onferent marine orgamsms as well as in marine samples. It is interest¬ing that there were some variations in !he number and nature of isomers of similar wax esters reported earlier. Long-chain wax esters are normally waxy in lIatllre alld their presence in fire coral plays a vital role in the nutrient transfer to the coral mass. They may also act as a protective coatillg of Ihe nematocyst of dactylozooid. The coral species were also subjected 10 mild acidic hydrolysis, followed by lIeutralization and partitioning between water and ether. The organic phase was dried and purified. by column chromatography and thin layer chromatography (TLe). Diphenylamille was revealed as the main product in one of the fractions. It is worth noting that diphenylamine is reported. for the first time as a marille natural prod¬uct. Diphenylamine is known to be toxic and causes allergic reactions to the skin, so it can be considered as responsible for the stinging property of fire coral
