Popis:	The structural elucidation of four phloroglucinol derivatives isolated from the ethanolic extract of the brown alga Carpophyllum angustifolium after peracetylation is described. Three of them, trihydroxyheptaphlorethol-A octadecaacetate, trihydroxyoctaphlorethol-A eicosaacetate and trihydroxyoctaphlorethol-B eicosaacetate, are described for the first time. Characterized by three additional hydroxyl groups and two 1,2-diphenoxylated 3,4,5-triacetoxybenzene rings directly linked by an ether bond they are called trihydroxyphlorethols as a novel group of phlorotannins. The structural elucidation was carried out on the basis of spectral data.
