Opis

Contents: T. Okuda, T. Yoshida, T. Hatano: Hydrolyzable Tannins and Related Polyphenols. - R.G. de Souza Berlinck: Some Aspects of Guanidine Secondary Metabolites. The volumes of this classic series, now referred to simply as "Zechmeister after its founder, L. Zechmeister, have appeared under the Springer Imprint ever since the series inauguration in 1938. The volumes contain contributions on various topics related to the origin, distribution, chemistry, synthesis, biochemistry, function or use of various classes of naturally occurring substances ranging from small molecules to biopolymers. Each contribution is written by a recognized authority in his field and provides a comprehensive and up-to-date review of the topic in question. Addressed to biologists, technologists, and chemists alike, the series can be used by the expert as a source of information and literature citations and by the non-expert as a means of orientation in a rapidly developing discipline.
