Tannins — Their Place in Plant Metabolism, such as lignans, phenolic acids, tannins, alkaloids, terpenoids etc. Excluding the structural polymers, the functions of many of these compounds (i.e., so-called secondary metabolites) are not well understood. This chapter presents an overview of the metabolism of phenylpropanoids, particularly hy

Biogenesis of Condensed Tannins — An Overviewuntered proanthocyanidin polymers, each of these biosynthetic proposals invoke isomerase enzymes or chemical intermediates not yet encountered in nature. Thus, substantial further study is required to clarify the pathways involved. An experimental program is proposed to achieve this objective.

Chemical Nature of Phlobapheneslso used to describe the red insoluble material produced by treating condensed tannins with mineral acid. The chemical composition of the “natural” phlobaphenes is complex and linked to other extraneous materials in addition to condensed tannins. Phlobaphenes are variable from plant source to plant

Conformational Analysis of Oligomeric Proanthocyanidinss at the interflavan bond and the conformation of the heterocyclic rings. The behavior of the heterocyclic rings can be determined by study of the monomers and dimers. The results obtained from x-ray diffraction and MM2 calculations are reviewed here. Conformations at the interflavan bond are studie

An Overview of Condensed Tannin Structurenins, phlobaphenes, and phenolic acids. Refining our understanding of the structure of polyflavonoids will lead to a better appreciation of their properties and help in developing their use as a renewable source of commodity and specialty chemicals. Considerable progress has already been made in the

Chromatography of Proanthocyanidinshy can be carried out using a variety of gel types. Often, repeated separations are required to obtain pure compounds, and it has been found advantageous to alternate each separation with a different gel type. Counter-current separation methods have seen limited application; however, with the develo

New NMR Experiments Applicable to Structure and Conformation Analysisr the past decade. This chapter summarizes these advances by describing how techniques including n.O.e. difference spectroscopy, homonuclear J-resolved and chemical shift correlation methods, and .C- and heteronuclear experiments have been applied to analyses of some example proanthocyanidins. These
