| chromatography in organic chemistry: Preparative Chromatography Techniques K. Hostettmann, Andrew Marston, Maryse Hostettmann, 2013-03-14 Over the past few years, increasing attention has been paid to the search for bioactive compounds from natural sources. The success of plant-derived products such as paclitaxel (Taxol) in tumor therapy or artemisinin in the treatment of malaria has provided the impetus for the introduction of numerous research programmes, especially in Industry. A great deal of effort is being expended in the generation of novel lead molecules of vegetable, marine and microbial origin by the use of high throughput screening protocols. When interesting hits are found, it is essen tial to have methods available for the rapid isolation of target compounds. For this reason, both industry and academia need efficient preparative chromatographic separation techniques and experience in their application. Purified natural products are required for complete spectro scopic identification and full characterization of new compo unds, for biological testing and for the supply of pharmaceuti cals, standards, and starting materials for synthetic work. Obtaining pure products from an extract can be a very long, te dious and expensive undertaking, involving many steps. Sometimes only minute amounts of the desired compounds are at hand and these entities may be labile. Thus it is an advantage to have access to as many different methods as possible in order to aid the isolation process. Although a certain amount of trial and error may be involved, nowadays there is the possibility of devising suitable rapid separation schemes by a judicious choice of the different techniques available. |

| chromatography in organic chemistry: Chromatography Toma J. Quintin, 2010 Chromatography is the collective term for a set of laboratory techniques for the separation of mixtures. It involves passing a mixture dissolved in a mobile phase through a stationary phase, which separates the analyte to be measured from other molecules in the mixture and allows it to be isolated. Chromatography may be preparative or analytical. The purpose of preparative chromatography is to separate the components of a mixture for further use (and is thus a form of purification). Analytical chromatography is done normally with smaller amounts of material and is for measuring the relative proportions of analytes in a mixture. This new and important book gathers the latest research from around the globe in the study of chomatography and herein highlights such topics as: analysis of veterinary drugs using chromatographic techniques, liquid chromatography for the determination of mycotoxins in foods, chromatography in the research of phenolic secondary metabolites, and others. |

| chromatography in organic chemistry: HPLC Toshihiko Hanai, 1999 How can these compounds be separated? Why was that method used? These are the two basic questions often asked by students of chromatography. HPLC: A Practical Guide provides the answers, enabling the reader to grasp the concepts of the technique using simple, representative chromatograms. Divided into six chapters, this practical guide covers basic concepts of HPLC; instrumentation; stationary phase materials; eluents; column efficiency; and the influence of physical chemistry on separations.

Uniquely, the descriptions of chromatographic separations are based on solubility using molecular properties, and solubility parameters are used to analyse the selections of chromatographic mode and column. Presenting the chemistry of liquid chromatography for undergraduate students, this valuable practical guide will also be useful for laboratory staff in industry and academia. |

| chromatography in organic chemistry: Chemical Derivatization in Analytical Chemistry R. W. Frei, James F. Lawrence, 1981-09 The first volume in this series is devoted to derivatization techniques in chromatography, for very obvious reasons. In gas chromatography (GC) chemical derivatization as an aid to expand the usefulness of the technique has been known for more than a decade and has become an established approach. The first chapter deals to a great extent with derivatization for the purpose of making compounds amenable to Gc. Although the discussion concentrates on pesticides, some generally valid conclusions can be drawn from this chapter. Chemistry will not be limited to the separation-it can also have a pronounced impact on the sample cleanup, another topic cov ered in Chapter 1. Since the introduction of coupled GC-mass spectroscopy (GC-MS), a very powerful tool, derivatization techniques have taken still another di rection-taking into consideration chromatographic as well as mass spec trometric improvement of the compounds of interest. Cyclic boronates are discussed as derivatization reagents for this purpose in the second chapter. |
