Phenol sulfate esters have been analyzed by paired-ion reversed-phase high-performance liquid chromatography. The method provided direct, rapid chromatography of phenol sulfates in crude extracts of the red alga (Polysiphonia lanosa (2,3-dibromo-4,5-dihydroxybenzyl alcohol 1',4-disulfate), of the brown alga Ascophyllum nodosum (1,2,3,5-tetrahydroxybenzene 2,5-disulfate), and in rat urine (resorcinol mono- and disulfates). Detector response (254 nm) was linear within the approximate range from 30--125 ng to 5--10 microgram. Semipreparative scale chromatography provided sufficient amounts of purified phenol sulfates for further analysis by paper electrophoresis.
