Separation Of Homologous And Isomeric Alkaloids Related To Nicotine On A Β-cyclodextrin-bonded Phase
Nicotine and thirteen structurally related alkaloids were separated with a β-cyclodextrin-bonded phase column. The retention of homologous compounds tends to increase as the size of the homolog increases. Structural isomers in which the pyridine nitrogen is in the 4-position are always retained the longest. Both retention and efficiency are very pH dependent. Conversely, selectivity does not change significantly with pH. © 1989.
