Book excerpt: Excerpt from Alkaloidal Estimation: A Bibliographical Index of Chemical Research, Prepared From Original Literature for the Committee of Revision The object of this work is to furnish a descriptive index of the work that has been done on the subject, rather than to abstract or summarize it. For convenience, as large a list of references is given for each article as is practicable, the first referring to the original publication, and the others to republications or abstracts. In preparing it, the following publications have been examined up to the end of 1897. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Book excerpt: Excerpt from The "Shaking Out" Method for the Quantitative Estimation of Alkaloids In most cases the alkaloid is separatei from the coloring matter, tannins, etc. By shaking the acid solution a few times with an immiscible organic solvent. Beal and Lewis1 pointed out that in this process several sources of error are introduced. in the first place, the alkaloidal salt may be slightly soluble in the organic solvent. There is also the possibility of the salt being hydrolysed.by'the water present into the free alkaloid ani the acid and in this case the free alkaloid wouli_be reaiily soluble in the solvent giving low results at the end.

Download or read book Studies on the Quantitative Estimation of Alkaloids by Means of Immiscible Solvents Classic Reprint written by Harry Fletcher Lewis and published by Forgotten Books. This book was released on 2017-12-13 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Studies on the Quantitative Estimation of Alkaloids by Means of Immiscible Solvents One of the oldest and most widely used methods of alkaloidal assay is based upon the general principle that alkaloids themselves are quite insoluble in water and soluble in organic solvents, while their salts are soluble in water and insoluble in the organic solvents. The method of alkaloidal determination based upon this principle is known as the shaking-out process familiar through its connection with the Dragendorff (1) method of plant analysis and the stas-otto (2) poison assay. It is assumed that the alkaloidal salt is practically insoluble in organic solvents and the alkaloid insoluble in neutral aqueous solutions. It also assumes that the salt is neither hydrolysed by the aqueous solution nor decomposed by the organic solvent. Both Dragendorff and Otto certainly realized that the principles were not absolute. Dragendorff made exception to the rule in the cases of the almost quantitative estimation of caffeine, and the removal of traces of veratrine by benzene and of theobromine, colchicine, papaverine, narceine and traces of narcotine by chloroform from acid aqueous solution of the alkaloids. Otto recognized the fact that ether took up traces of colchicine, papaverine, narcotine, veratrine, and atropine from their acid solution.

Download or read book Alkaloids written by Hans-Ferdinand Linskens and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is refreshing to find a book treating alkaloid analysis with all the latest techniques such as inverse-detected two dimensional NMR, GC/MS, and HPLC associated techniques. There have been many developments in the field of alkaloid analysis since the 1950s, not the least of which are the various powerful spectroscopic methods, which dominate this volume. Included also are the various aspects of tobacco alkaloids and analysis in various situations. The complexities of sampling and analysis in tobacco smoke is explained. Analysis of alkaloids produced by tobacco root cell cultures is included, while genetic and chemical analysis is described for Papaver, a plant of considerable medicinal significance.
