Based on the assumption that the sugar in parotin is mannose, the amount of sugar contained in parotin of approximately 93% purity was 0.73%. Less pure parotin, recovered from the precipitation mother liquor, obtained during the purification of parotin, contained 1.78% of sugar. From these results, it is assumed that the sugar content of parotin itself is in a range of 0.79 to 0.48%. It is also assumed that hexos amine is either nonexistent or is contained in a minute amount, and that a very minute amount of pyrrole dye is contained in parotin preparation.
