The possibility of using the phenol-sulfuric acid method for the determination of total glycogen, its acid-soluble and acid-insoluble fractions in the liver and skeletal muscles of rats was studied. It was found that the use of a precipitant in the isolation of total glycogen and its fractions increases the yield of the investigated substances. Key words: phenol-sulfate method, rats, liver, muscles, total glycogen, acid-soluble glycogen, acid-insoluble glycogen.

Sulfuric Acid Method

Abstract A newly developed indirect method for lignin, utilizing permanganate, permits the determination of cellulose and insoluble ash in the same sample. The new permanganate lignin method is intended as an alternative procedure to the 72% sulfuric acid method over which it offers definite advantages as well as certain disadvantages. Choice of methods will depend upon the materials analyzed and the purpose for which the values are to be used.
