Available in PDF, EPUB and Kindle. Book excerpt: Given the growing importance of essential oils and waxes, this volume deals with the analysis of a broad spectrum of these compounds from many plant origins. Commercial oils such as olive oil are analysed as are trees such as eucalyptus, mentha, cedar and juniper. In addition, analysis of spices, seasoning, seaweeds, perfumes, liquors and atmospheric monoterpene hydrocarbons are to be found in this book. The volatiles of flower and pollen may be of importance in attraction of bees and other insects to certain plants for pollination purposes; this topic is also discussed. Waxes, both in the soil and as leaf components are analysed and presented in such a way making this book valuable to scientists with varying interests worldwide.

This book was released on 1998-04-30 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This long awaited third edition of Phytochemical Methods is, as its predecessors, a key tool for undergraduates, research workers in plant biochemistry, plant taxonomists and any researchers in related areas where the analysis of organic plant components is key to their investigations. Phytochemistry is a rapidly expanding area with new techniques being developed and existing ones perfected and made easier to incorporate as standard methods in the laboratory. This latest edition includes descriptions of the most up-to-date methods such as HPLC and the increasingly sophisticated NMR and related spectral techniques. Other methods described are the use of NMR to locate substances within the plant cell and the chiral separation of essential oils. After an introductory chapter on methods of plant analysis, individual chapters describe methods of identifying the different type of plant molecules: phenolic compounds, terpenoids, organic acids, lipids and related compounds, nitrogen compounds, sugar and derivatives and macromolecules. Different methods are discussed and recommended, and guidance provided for the analysis of compounds of special physiological relevance such as endogenous growth regulators, substances of pharmacological interest and screening methods for the detection of substances for taxonomic purposes. It also includes an important bibliographic guide to specialized texts. This comprehensive book constitutes a unique and indispensable practical guide for any phytochemistry or related laboratory, and provides hands-on description of experimental techniques so that students and researchers can become familiar with these invaluable methods.

Available in PDF, EPUB and Kindle. Book excerpt: Modern Methods of Plant Analysis When the handbook Modern Methods ofPlant Analysis, was first introduced in 1954, the considerations were: 1. the dependence of scientific progress in biologyon the improvement of existing and the introduction of new methods; 2. the difficulty in finding many new analytical methods in specialized journals which are normally not accessible to experimental plant biologists; 3. the fact that in the methods sections of papers the description of methods is frequently so compact, or even sometimes so incomplete, that it is difficult to reproduce experiments. These considerations still stand today. The series was highly successful, seven volumes appearing between 1956 and 1964. Since there is still today a demand for the old series, the publisher has decided to resume publication of Modern Methods ofPlant Analysis.It is hoped that the NewSeries willbejust as acceptable to those working in plant sciences and related fields as the early volumes undoubtedlywere.It is difficult to single out the major reasons for the success of any publication, but we believe that the methods published in the first series were up-to-date at the time and presented in a waythat made description, as applied to plant material, complete in itselfwith little need to consult other publications. Contribution authors have attempted to follow these guidelines in this New Series of volumes. Editorial The earlier series of Modern Methods ofPlant Analysis was initiated by Michel V.

Book excerpt: If, following the solvent extraction of a hydrocarbon from a plant, it is not known whether it is one or the other, a method of distinguishing the two is described by HENDRICKS, WILDMAN and JONES (1946). The technique involves the infra-red absorption spectra of the two isomers. At about 12 mp. the relative absorption coefficient of rubber is 42% greater than for gutta. ScHLESINGER and LEPER (1951) describe two procedures for separation of the rubber and gutta hydrocarbons from large quantities of crude chicle. In one, the chicle is extracted with benzene which dissolves both isomers. An excess absolute ethyl acetate is added and the mixture stored at 5° C overnight. The gutta precipitates out and the rubber remains in solution. The other method is as follows: (1) Ten grams of chicle are extracted with acetone for 24 hours in a Soxhlet extraction apparatus. (2) The insoluble material in the thimble is allowed to .. it dry, then immersed in 150 ml. of cold Skellysolve B in a refrigerator at 10° C and· allowed to stand for 48 hours with occasional agitation. (3) The thimble is then removed from the solvent and the enclosed residue washed several times with fresh, cold Skellysolve B. (4) An excess of acetone and a few drops of a concentrated aqueous solution of sodium iodide are added to the combined Skellysolve B extract and washings and allowed to stand overnight in a refrigerator.

PREFACE The industry and science of essential oils have undergone within the last two decades more changes than could have been anticipated by those writers who, during the 1920 s, contributed so valuably to our knowledge of this field. It is, therefore, no derogation of the works of Gildemeister and Hoffmann, Parry, Finnemore, and others, to state that the time is past due for bringing the whole subject up-to-date. This is the authors motive for the present treatise on the production, chemistry, analysis and appli cation of these interesting and important products. It seems particularly fitting that this work be published in the United States, which, as the largest user of essential oils, lias the most vital concern in the progress and ex pansion of the essential oil industry. Within the last ten years and largely as a result of World War II there have taken place fundamental developments within the field, especially with respect to new sources of supply in the Western Hemisphere. It has been the authors rare privilege to witness most of these developments at first hand. His travels for more than twenty years have taken him the length and breadth of Europe, through Africa, Asia, Australia, into the new producing centers of North, Central and South America in all of which places he surveyed the production of essentialoils at their source. The original purpose of this systematic survey was to snpply Fritzsche Brothers, Inc., of New York, the essential oil industry in general, and Gov ernment agencies with exhaustive data on the production of essential oils. In the course of this work the author collected countless samples of authen tic oils, produced under his supervision and of guaranteed purity...

Available in PDF, EPUB and Kindle. Book excerpt: Molecular Methods of Plant Analysis Concept of the Series The powerful recombinant DNA technology and related developments have had an enormous impact on molecular biology. Any treatment of plant analysis must make use of these new methods. Developments have been so fast and the methods so powerful that the editors of Modern Methods of Plant Analysis have now decided to rename the series Molecular Methods ofPlant Analysis. This will not change the general aims of the series, but best describes the thrust and content of the series as we go forward into the new millennium. This does not mean that all chapters a priori deal only with the methods of molecular biology,but rather that these methods are to be found in many chapters together with the more traditional methods of analysis which have seen recent advances. The numbering of the volumes of the series therefore continues on from 20, which is the most recently published volume under the title Modern Methods ofPlant Analysis. As indicated for previous volumes, the methods to be found in Molecular Methods ofPlantAnalysis are described critically,with hints as to their limitations, references to original papers and authors being given, and the chapters written so that there is little need to consult other texts to carry out the methods of analysis described. All authors have been chosen because of their special experience in handling plant material and/or their expertise with the methods described.

Download or read book Instrumental Methods in Food and Beverage Analysis written by D.L.B. Wetzel and published by Elsevier. This book was released on 1998-05-29 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in instrumentation and applied instrumental analysis methods have allowed scientists concerned with food and beverage quality, labeling, compliance, and safety to meet ever increasing analytical demands. Texts dealing with instrumental analysis alone are usually organized by the techniques without regard to applications. The biannual review issue of Analytical Chemistry under the topic of Food Analysis is organized by the analyte such as N and protein, carbohydrate, inorganics, enzymes, flavor and odor, color, lipids, and vitamins. Under 'flavor and odor' the subdivisions are not along the lines of the analyte but the matrix (e.g. wine, meat, dairy, fruit) in which the analyte is being determined. In "Instrumentation in Food and Beverage Analysis" the reader is referred to a list of 72 entries entitled "Instrumentation and Instrumental Techniques" among which molecular spectroscopy, chromatographic and other sophisticated separations in addition to hyphenated techniques such as GS-Mass spectrometry. A few of the entries appear under a chapter named for the technique. Most of the analytical techniques used for determination, separations and sample work prior to determination are treated in the context of an analytical method for a specific analyte in a particular food or beverage matrix with which the author has a professional familiarity, dedication, and authority. Since, in food analysis in particular, it is usually the food matrix that presents the research analytical chemist involved with method development the greatest challenge.
