Sentence Examples with the word quinidine

Traces of quinidine are also sometimes, though rarely, found in commercial quinine, but its presence does not detract in a medicinal point of view from the value of the latter.

Later quinidine and cinchonidine were discovered, and subsequently several other alkaloids, but in smaller quantity.

The other alkaloids are distinguished from quinine thus: quinidine resembles quinine, but is dextro-rotatory, and the iodide is very insoluble in water; the solution of cinchonidine, which is laevo-rotatory, does not give the thalleoquin test, nor fluorescence; cinchonine resembles cinchonidine in these respects, but is dextrorotatory.
