| dc.description.abstract | A method is described for the separation of
organic poisons - alkaloids, other bases, glucosides
and barbiturates. It depends on extraction of the
poison and removal of fats and proteins by trichloracetic acid; adsorption of the bases on Novasorb
or kaolin and of the non -basic substances on charcoal; and extraction from the adsorbent by
chloroform, ether, etc. under suitable conditions. | en |
| dc.description.abstract | Evidence is advanced to show that removal of
the poison at each stage is complete. | en |
| dc.description.abstract | Figures are given for the percentage recovery
of various poisons (a) when added to meat, (b) when
the poison has been injected into an animal. | en |
| dc.description.abstract | Results by the new method are compared with
those by the standard Stas -Otto process. It is
shown that the new method (a) gives better percentage
recovery in most cases, (b) represents a very
considerable saving of time and labour, (c) yields
a purer product from the solution in immiscible
solvent. | en |
| dc.description.abstract | Experiments are described to show the limits of
sensitivity of the extraction process, its use in
separating two organic poisons present together, etc. | en |
| dc.description.abstract | The method can be applied for extraction of
alkaloids from natural sources. | en |
