BOOK REVIEWS Gas Chromalogra$lzy Abstracts rg@ (references to the end of rg$3), compiled and edited by C. E. H. KNAPMAN, Assistant Editor C. G. SCOTT, Butterworths Scientific Publications, London, 1960, 262 pages, price 42 s. This work Was compiled from three independent bibliographies of members of the Gas Chromatography Discussion Group. It is intended to serve as an inaugural volume of Gas Chromatogra#v%y Abstracts which is planned to appear annually. The volume under review consists of the bibliography up to the end of 1958 and contains 1465 references with the complete title of the paper, the reference, its reference in Chemical Abstracts, as well as a short paragraph describing its contents. The number of references appears rather large at first sight when compared with only 619 references in the review by HARDY AND POLLARD (this journal, Vol. 2 (1959) L) for almost the same period. However, not only gas-liquid chromatography is abstracted here but also gas adsorption chromatography and numerous papers dealing with chromatography, gas adsorption or gas analysis in general. The editors are to be congratulated for compiling these abstracts. In a field such as gas chromatography, in which about five hundred papers are published annually, text books and review articles will always need such annual volumes as supplement. Such a compilation is also justified although it duplicates in a sense the work: of Chemical Abstracts and Analytical Abstracts, since most information can be gained here by consulting only one subject index, which incidentally is very Well prepared. The reviewer found very few printer’s errors, and no important references seemed to be missing. J. C?LYOWZtOg., 4 (1960) ~$27
Papierc~romatographie iu der Botanik, 2nd Ed., edited by H. F. LINSKENS, published by Springer-Verlag, Berlin, Gijttingen, Heidelberg, 1959, 405 pages, 124 figs., 2 coloured plates, price D.M. sS.-. This second edition reflects great credit on the editor and his 23 co-authors. The first edition, of 1955, has been expan.ded from 243 to-394 pages, and the number of contributors has been increased from 13 to 23, the present authors including no less than II, of the original ones. In the introductory section a brief but very clear exposition of the theory of paper chromatographic separations is followed by excellent sections on laboratory equipment’ and techniques, with many illustrations and practical instructions. Sources of error, types of paper, the .pretreatment of papers;- the estraction and preparation of samples, from plant materials,’ the. removal of interfering substances, the applicaT,tions of isotope techniques are all reviewed fairly fully, always with emphasis on the practical aspects. Throughout the book, paper electrophoresis is given as important i place’ as paper chromatography. ,

BOOK REVIEWS
The remainder of the boolc comprises chapters on the following special topics: Inorganic anions and cations ; Carbohydrates ; Organic acids ; Lichen acids ; Phosphatides and complex lipids; Proteins and their building blocks; Nucleic acids and their building blocks ; Plant viruses ; Pigments; Growth substances and related compounds, and vitamins; Antibiotics and tosins; Aldehydes and lcetones; Phenols and tannins; Organic bases, including alkaloids; Sterols and related compounds; Detection of steroids by colour reactions. There is remarkable consistency in the high,quality, the comprehensiveness and the laybut,.of these chapters. In most of them, methods of extraction and preparation for chromatography, of the substances in question are reviewed critically, chromatographic or electrophoretic separations, methods of detection of spots and quantitative determinations are discussed, and comprehensive tables of RF values are given. For biologically active compounds, bioassay methods and their application to spots on chromatograms, or eluates of these, are discussecl. The many references to the literature appear to be well chosen. One feels that more cross-references would be helpful. For esample, desalting is mentioned briefly on p. 6, but there is no reference there to the valuable discussion of apparatus and techniques which appeax% on pp. 32-34, or of thkir application to amino’ acids on pp. 150-151. Continuous (curtain) electrophoresis is not treated in detail in the intrpductory section, though references to the use of this important technique of course appear later -in the chapter on plant viruses, for esample. For staining peptide spots on paper, ninhydrin only is mentioned; the chlorine-starch’ iodide method of RYDON AND SRIITI-I (Nattire, 169 (1952) 922) is more sensitive as a general stain, and of course other stains are invaluable for particular groups of peptides. The reviewer feels that in addition to providing a valuable handbook on the paper-chromatographid separation of plant materials, this book will furnish a useful supplement to esisting works on the estraction and isolation of plant constituents.
