Paperback. Condizione: New. Print on Demand. This book presents a detailed methodology for estimating the strength of crude drugs, pharmaceutical compounds, and their preparations by employing Mayers reagent, a chemical solution used to detect and quantify alkaloids. The author begins by providing a list of equipment and reagents necessary for carrying out these assays, and then proceeds to describe various methods for extracting alkaloids from plant material. The book then details the general assay processes: three methods recommended by the author, and one method from the author's contemporary, Adolph Dragendorff. In each of these general assay processes, the author provides step-by-step instructions for quantifying alkaloids using Mayers reagent. The author also discusses the importance of obtaining a fair average sample of the drug and the choice of solvent for the most effective extraction of alkaloids. The book's greatest strength is its practicality - the author has designed the methods with a minimum amount of time and equipment required, making them accessible to pharmacists and researchers alike.
