Scientists from the National Institutes of Health have isolated and determined the structures of many of the compounds present in these skin secretions using the techniques of mass spectrometry and NMR spectroscopy (Chapter 1 2). Thus far, the structures of close to 200 different alkaloids have been determined. The most potent of these toxins is batrachotoxin (from Phyllobates ter-rlbllls), an example of a steroidal alkaloid. Other toxins include... 

Dr. Crabb has updated his review on alkaloids which appeared in Volume 6A of this series. This valuable report includes a timely account of the published work on indole alkaloids. A previous review on the 13C NMR spectroscopy of steroids has been brought up to date by Professor W. B. Smith. The more theoretical aspects of dynamic NMR are covered by Dr. Witanowski and his co-workers. Finally, it is a pleasure to include a review on 119Sn NMR spectroscopy for the first time in this series. 

A useful compendium of data on isoquinoline alkaloids has been published, this second volume bringing literature coverage in the series up to 1972. An introductory section deals with recent structure determinations, syntheses, and biogenetic correlations. A more general compilation includes new alkaloids described in 1973. The structure and absorption spectroscopy of steroids and alkaloids are the subject of another volume. Outstanding items in alkaloid literature during 1973 have been summarized. ...
