Comparative Microscopic Tests of Anabasine and its Related Compounds, its Purification, and some Physical Constants
- 14 Downloads
Since the physical constants varied for each distilled fraction, it is hardly possible to name any specific fraction as pure anabasine, entirely free from lupinine and other impurities. However, the comparative microscopic tests on various fractions would indicate that pure anabasine is between the fractions number 8 and 14.
All of the microscopic tests for anabasine produced crystals very similar to those of nicotine. The most distinctive test for anabasine is the gold chloride test. The crystals formed with gold chloride differ from those produced with gold chloride and nicotine.
The authors wish to acknowledge the assistance of Mr.G. H. Fleming for performing the distillation and for valuable suggestions throughout the work.
