This book was released on 1989 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: A revisao taxonomica do genero Kielmeyera Martius permitiu uma avaliacao detalhada das suas caracteristicas morfologicas. Este estudo mostra que especies de Kielmeyera sao bastantes diversificadas em seus caracteres vegetativos e florais. Dentro de todas as caracteristicas examinadas, em um total superior a quatro mil especimes herborizados, o habito e os caracteres vegetativos evidenciaram-se com o maior grau de diversidade. Neste trabalho, os atributos morfologicos externos sao considerados basicos para a identificacao e a classificacao das especies de Kielmeyera; todavia, informacoes suplementares oriundas de outras disciplinas auxiliaram na conclusoes alcancadas no tratamento taxonomico do genero. Variacoes na morfologia externa, no habito e na fenologia, intra-especificamente, sao topicos estudados pelo autor em frequentes e extensivos trabalhos de campo em inumeras e diferentes localidades brasileiras com o objetivo de analisar as especies in loco. Consequentemente, este estudo permitiu a observacao de populacoes naturais de muitas especies de Kielmeyera dentro dos seus parametros de distribuicoes geografica e ecologica. Em contraste as caracteristicas vegetativas, as flores exibem importantes e confiaveis caracteres morfologicos com valores diagnosticos e taxonomicos. A morfologia dos frutos de Kielmeyera e muito constante em quase a totalidade das especies. Nesta publicacao, as caracteristicas exomorficas em relacao a taxonomia do genero Kielmeyera estao apresentadas em detalhes.

Download or read book Diversity and Classification of Flowering Plants written by Armen Leonovich Takhtadzhi͡an and published by Columbia University Press. This book was released on 1997 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: The culmination of more than fifty years of research by the foremost living expert on plant classification, Diversity and Classification of Flowering Plants is an important contribution to the field of plant taxonomy. In the last decade, the system of classifying plants has been thoroughly revised. Instead of describing every individual family, Takhtajan includes descriptions in keys to families, which he calls "descriptive keys." The advantage of descriptive keys is that they give both the characteristic features of the families and their differences. The delimitation of families and orders drastically differs from the one accepted by the Englerian school and from the one accepted in Arthur Cronquist's system. Takhtajan favors the smaller, more natural families and orders, which are more coherent and better-defined, where characters are easily grasped, and which are more suitable for information retrieval and phylogenetic studies, including cladistic analysis (because it reduces polymorphic codings).

Download or read book Chemistry And Biology Of Ellagitannins An Underestimated Class Of Bioactive Plant Polyphenols written by Stephane Quideau and published by World Scientific. This book was released on 2009-01-05 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first of its kind that focuses on the chemistry and biology of ellagitannins, a special class of naturally occurring polyphenols which have so far not received the attention they deserve. These polyphenolic substances are found in many plants, including numerous food sources. They not only exhibit unique structural features that fascinate most chemists who are aware of their existence, but also express remarkable biological activities that have yet to attract the interest of the pharmaceutical industry. This is surprising because ellagitannins have been identified as active principles in traditional Chinese medicines.The principal aim of this book is to set the record straight. Most, if not all, worldwide experts in each aspect of the chemistry and biology of this underestimated class of natural products have contributed to this book. It covers topics such as their structural determination and natural occurrence; the most up-to-date knowledge of their biosynthesis; the current state of the art of their total chemical synthesis; their main physicochemical properties and principal biological activities; their presence in food and beverages; and their related health effects. All together, nine chapters compose this book whose content is placed into historical perspective in a yet inspiring preface written by one of the pioneers in modern polyphenol research, Professor Edwin Haslam. This book will be useful not only to scientists involved in natural product research, but also to lecturers and their students as a source of key references and/or a textbook.

This book was released on 2012-12-06 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: For several decades botanists have been impressed by the discovery that the distribution of secondary plant substances follows the general lines of plant relationships. However, it soon became clear that little was to be gained from the study of individual compounds and their natural distribu tion. Therefore, more comprehensive studies were attempt ed in which the secondary chemistry of a major plant group was carefully studied and evaluated in the broader context of comparative phytochemistry. Holger Erdtman's admir able work on Coniferae is the foremost example of this kind. Since then, there has been an upswing in the study of the biosynthesis of secondary plant substances and it has become quite customary to make use of biosynthetic knowledge in interpreting chemosystematic evidence. More over, since taxonomists have insisted that use be made of all potentially available evidence for building classifications, it has been claimed that chemosystematics too should con sider the whole array of constituents present in a major taxon. However, in practice it has proved difficult to utilize fully the potential of natural product chemistry and biosynthetic studies for plant systematics and evolution, because bota nists found themselves rather disorientated by the scattered, often hardly accessible chemical literature and the fact that the chemical evidence was difficult for them to evaluate! Although the pioneering work of E. C.
