Resumo

This study reports for the first time the extraction and quantification of sterols in four red macroalgae from Antarctica: Palmaria decipiens, Plocamium cartilagineum, Iridaea cordata and Pyropia endiviifolia. The extraction of sterols involves alkaline hydrolysis from algal biomass and the quantification of cholesterol, brassicasterol, ergosterol, campesterol, stigmasterol, β-sitosterol and fucosterol were performed by Gas Chromatography coupled with Mass Spectrometry (GC-MS). In general, cholesterol was the most abundant compound (216.32 to 3195.69 mg kg-1), followed by β-sitosterol (131.42 to 654.18 mg kg-1), stigmasterol (68.35 to 393.20 mg kg-1), brassicasterol (68.56 to 337.43 mg kg-1), campesterol (64.95 to 277.78 mg kg-1) and fucosterol (57.67 to 286.18 mg kg-1). Ergosterol was not quantified in all samples analyzed while brassicasterol was not quantified in Iridaea cordata, but it was quantified in the other three samples.
