- n. Atropine; -- called also daturia and daturina.
from The Century Dictionary and Cyclopedia
- n. A poisonous alkaloid found in the thorn-apple. See Datura. Same as atropin.
It is true that Schmidt had received pure atropine under the name of daturine, for I have proved most conclusively that the so-called daturine supplied by Trommsdorff, of Erfurt, is pure atropine and nothing else.
I also tried in the same manner the alkaloid sold as daturine, which is believed not to differ from atropine, and it produced no effect.
Planta has already tried to show that atropine is identical with the daturine obtained by Geiger and Hesse, founding his opinion on facts which we nowadays look upon as doubtful.
I have also shown that Merck's daturine differs from atropine, and is merely pure hyoscyamine.
This eminent manufacturer was good enough to comply with my request, and sent me two products, one of which was marked "light daturine," the other
The "heavy daturine," of which only a small quantity is obtainable, is far from being a body of definite composition, that is to say, it is a mixture of atropine and hyoscyamine.
A short time afterward there appeared a paper by Schmidt which again asserted the identity of daturine and atropine.
I have succeeded in splitting up "heavy daturine" by two different methods.
I thought it as well, therefore, to recommence the study of daturine, the more so as I had already determined the incorrectness of the long accepted point of fusion of atropine, and that my researches on hyoscyamine convinced me that this base is an isomer of atropine, although very analogous to it.
I need only mention that slight poisonings by means of chloroform, morphine, atropine, daturine, decrease, and that strychnine increases the sensitivity of the touch organ.
