The presence of contaminant flavonoids in vitamin C preparations from citrus fruits initially led Szent-Gyorgyi and his collaborators to suggest that a flavonoid compound, with biological activity for the prevention of capillary fragility, was vitamin P. Later re search, although not disproving biological activity, discontinued the use of the vitamin classification for these compounds. However, the ubiquitous distribution of flavonoids in living organisms, and the continued discovery of various activity in biological systems makes these compounds targets of wide ranging investigation. This volume is primarily based on a Symposium on Flavonoids and related com pounds held during the 212th National Meeting of the American Chemical Society held in Orlando, Florida on August 28-29, 1996 under the sponsorship of the Division of Agricul tural and Food Chemistry. While the book is not intended to be a comprehensive volume on flavonoid research, the papers provide various approaches to exploring the biological functions of flavonoids in plants and animals, their chemical modifications for enhanced activity, some analytical techniques, as well as their use in food classification. A signifi cant portion is devoted to medicinal implications of these compounds. The organizers would like to express their appreciation to Tropicana Products, Inc., Bradenton, Florida, Coca-Cola Foods Division, Plymouth, Florida and the American Chemical Society's Division of Agricultural and Food Chemistry for financial support. Of course, the book could not be produced without the authors, whose cooperation and pa tience is greatly appreciated.

The major purpose ofthis third volume in The Flavonoidsseries is to provide a detailed review of progress in the field during the five years, 1981-1985 inclusive. It thus continues the comprehensive coverage of the literature on these fascinating and important plant pigments which began in 1975 with the publication of The Flavonoids and which was followed in 1982 with The Flavonoids: Advances in Research. As with the two previous vo1umes, this one is entire1y se1f-contained and where necessary tabu1ar data and references from earlier vo1umes are included and expanded here. A unique feature is the complete listing in the Appendix ofall known flavonoids, which now number over 4000 structures; in this list, structures newly reported during the period 1981-1985 are so indicated. The first ten chaptersofthis book provide a critical review ofthe new substancesthat have been discovered among each of the main classes of flavonoid during the period under review. Again, the numberofnew isoflavonoids reported outweighs that ofother classesand ahundred pagesare needed to describe all the nove1 findings. Neoflavonoids, which were omitted in the first supplement, have been included again and a special chapter on miscellaneous flavonoids has been introduced to cope with those structures (e.g. homoisoflavonoids) which do not fit in easily anywhere else. Although there have been advances in flavonoid methodology, these have not been asspectacular as in earlier years. Hence, literature reports on new chromatographic and spectral procedures are included here in the individual chapters under the different flavonoid classes.
