Abstract
In a former paper 1 we have already communicated that the inosin which we obtained from inosinic acid was identical with that obtained from karnin by Haiser and Wenzel. 2 We have now succeeded in isolating from inosin the pentose in a crystalline state. The properties of this sugar are as follows: Melting point 87° C. Its rotation in aqueous solution is (d) D = —19°.4. The osazone melts at 163°-164° C. and shows a rotation when 0.2 gram are dissolved in 10 c.c. of a mixture of four parts pyridine to six parts of alcohol of (d) D = — 0°.92. The benzylphenylhydrazone melts at 128° C. and in absolute alcoholic solution rotates (d) D = —26°.46.
