Also for the first time ‘‘Chromone Alkaloids” and ‘ ‘DibenzopyrrocolineA lkaloids” are presented, many of them having interesting pharmacological properties, The “Lupine Alkaloids” were discussed in Vols. 3, 7, and 9 of this treatise. This classical group of alkaloids is updated here and presented by experts in the field. “Alkaloids from Ants and Other Insects” presents compounds discussed earlier under ‘ ‘Piperidine Alkaloids,’ ’ ‘‘Pyrrolizidine Alkaloids ,” “Simple Indo- lizidine and Quinolizidine Alkaloids, ’ ’ and “Pyrrolidine Alkaloids, ’ ’ now con- densed in one chapter summarizing these interesting natural products. “Pavine and Isopavine Alkaloids, discussed under the heading ‘‘Isoquinoline Al- ” kaloids” in Vols. 12 and 17 of this treatise, now comprises more than two dozen alkaloids, justifying their presentation as a separate group of isoquinoline al- kaloids. Occurrence, spectral properties, structures, and synthesis and bio- synthesis are professionally covered, and pharmacological properties included whenever known. Arnold Brossi ix
