In this study, a method for extracting and concentrating glucosylceramide, which has promising applications in cosmetics and food, from marine products was examined. While glucosylceramide was not contained in the livers or viscera of salmon, octopus or scallop, 0.38 and 0.16 wt% of the substance was contained in starfish and sea cucumber viscera, respectively, with a structure differing from that found in cattle brain, rice bran, corn and other plants. A concentrate containing 50% or more of glucosylceramide was created via an extraction and concentration process combining ethanol extraction and alkaline hydrolysis. These results indicate that starfish and sea cucumber viscera are promising sources of glucosylceramide.
