Some Chemical Constituents of the Mussel (<i>Mytilus edulis</i>)

Abstract

TISSUES of the common sea-mussel (Mytilus edulis), macerated in 60 % alcohol, during another investigation gave an extract which, after filtering and further addition of alcohol, deposited clusters of colourless crystals on standing. Experiment showed that this crvstalline substance was much more soluble in water than in alcohol and could always be thrown out by further addition of alcohol to the tissue-extracts. Within a range of 70-80 % alcohol, two distinct crystalline forms were observed together with a certain amount of brownish coloured gummy material. At alcoholic strengths nearer to 70 %
