Alkaloids

It is refreshing to find a book treating alkaloid analysis with all the latest techniques such as inverse-detected two dimensional NMR, GC/MS, and HPLC associated techniques. There have been many developments in the field of alkaloid analysis since the 1950s, not the least of which are the various powerful spectroscopic methods, which dominate this volume. Included also are the various aspects of tobacco alkaloids and analysis in various situations. The complexities of sampling and analysis in tobacco smoke is explained. Analysis of alkaloids produced by tobacco root cell cultures is included, while genetic and chemical analysis is described for Papaver , a plant of considerable medicinal significance.
