TAILIEUCHUNG - Plant Drug Analysis: A Thin Layer Chromatography Atlas

This second edition of Plant Drug Analysis includes more than 200 updated color photographs of superb quality demonstrating chromatograms of all relevant standard drugs. All drugs presented meet the standard of the official pharmacopoeia and originate from well-defined botanical sources. With this guide the technique of thin layer chromatography can be easily used without previous pharmacognostic training. Only commercially available equipment and reagents are needed, the sources as well as all practical details are given. . | H. Wagner s. Bladt plant DRUG ANALYSIS A Thin Layer Chromatography Atlas Photographs by V. Rickl Second Edition Springer Preface to the Second Edition More than 12 years have passed since the first and very successful attempt was made to reproduce the thin layer chromatography TLC separation of 170 medicinal plant drugs in the form of color TLC fingerprints in a book. The reproduction of natural color photographs in ƯV 365 nm was a difficult undertaking at that time due to the relatively unsophisticated film and filter technology. The first German edition of this book with its appended English translation met with worldwide acceptance in the field of natural product chemistry and has remained an indispensable aid in the laboratory analysis of medicinal drugs. Due to the higher demands now placed on plant drug quality the introduction of herbal preparations with medicinal significance and the increasing number of phytochemical preparations the analytical and standardization procedures of the plants have gained even greater importance. We have tried to do justice to this development in this second edition. This TLC atlas now includes about 230 medicinal plants of worldwide interest. The photographs of the TLC fingerprints and the descriptions of the characteristic compounds of each plant extract are a quick and reliable source for the identification and purity check of plant material and phytopreparations. Most of the TLC systems are standard systems and have been optimized when necessary. In spite of other available analytic techniques such as gas chromatography and high performance liquid chromatography TLC still remains a most useful quick effective and low-cost method for the separation and identification of complex mixtures of herbal drug preparations and plant constituents. The authors are most grateful to Ms. Ute Redl for her comprehensive technical assistance. We also thank Ms. Veronika Rickl not only for the excellent quality of the photographs but also .
