Origin of cinchonine
Examples from the Web for cinchonine
When cinchonine is distilled with solid potassium hydrate, it yields pyrrol and bases of both the pyridine and quinoline series.
The presence of cinchonine may also be positively determined by reference to the behaviour of that alkaloid.
Cinchonine may be prepared from its sulphate or disulphate in the same way as quinine.
The operation is then repeated, the ether being replaced by chloroform in which both quinine and cinchonine are soluble.Legal Chemistry|A. Naquet
If this be quinidine, it will be dissolved on the addition of proportionately more ether, while cinchonine will remain unaffected.
