Green alga caulerpa racemosa: Is it possible to use (high performance liquid c) HPLC for its toxicity testing?

currently i’m doing reserach in green alga caulerpa racemosa.. i’m looking for any journal or article regarding usage of HPLC (high performance liquid chromatography) for its toxicity testing.
This type of green alga being one of the local food near langkawi island, malaysia and invasive for other plants as well.

As I understand it, toxicity testing is putting a plant or something else into water and then seeing if the water (or sediment or some chemical) is toxic to it. I’m not sure how you could use HPLC for toxicity testing that way as it is measuring a compound. Perhaps you are looking for a toxic compound? As you can see, I am familiar with toxicity testing, somewhat with HPLC, and not with Caulerpa.

As far as looking for articles, have you done a search on Science Direct or any of the other science search engines? I always found looking for an article that was similar was the best way, and then looking at the references.

HPLC in Enzymatic Analysis


HPLC in Enzymatic Analysis


$305


The use of High Performance Liquid Chromatography (HPLC) techniques in the study of enzymatic reactions has grown significantly since the publication of the first edition of this highly successful book: the role of enzymes in biological research has expanded; the application of HPLC and enzymes has extended to more disciplines; advances in separation techniques and instrumentation have increased the capability of HPLC; and the discovery of new enzymes has spawned new methods of analysis. High Performance Liquid Chromatography in Enzymatic Analysis, Second Edition addresses these developments in its coverage of the refinements of HPLC methods and their use in a wide range of laboratory applications. It offers the same practical approach found in the first edition, incorporates a wealth of new information into existing chapters, and adds new chapters to deal with new applications, including capillary electrophoresis, forensic chemistry, microdialysis, and the polymerase chain reaction. Topics include:. * Application of HPLC to the assay of enzymatic activities. * Concepts and principles of HPLC, including the latest technological advances. * Concepts and principles of capillary electrophoresis (CE). * Strategy for design of an HPLC/CE system for assay of enzyme activity. * Preparation of enzymatic activities from tissues and single cells. * Analysis of enzymatic activities in body fluids, including chromatobiosis. * HPLC for the identification of new enzymatic activities. * Fundamentals of the polymerase chain reaction. * HPLC in forensics. * Survey of enzymatic activities assayed by the HPLC method, including many new categories. * Multienzyme systems, including many new examples. * HPLC in the analysis of contaminated food. “It is the ability of HPLC to accomplish separations completely and rapidly that led to its original application to problems in the life sciences, particularly those related to purification. An analysis of the literature revealed that this technique was used primarily for the purification of small molecules, macromolecules such as peptides and proteins, and more recently, antibodies. This application to purification has all but dominated the use of the method, and there has been a plethora of books, symposia, and conferences on the use of HPLC for these purposes. However, it was only a matter of time before others began to look beyond and to explore the possibilities that result from the capacity to make separations quickly and efficiently.” –from the preface to the First Edition. Easy to read and full of practical advice and hundreds of diagrams and examples, High Performance Liquid Chromatography in Enzymatic Analysis, Second Edition is an invaluable resource for students, researchers, and laboratory workers in analytical chemistry and biochemistry, molecular biology and cell biology, and for anyone interested in keeping up with this fast-growing field.

Quantitation of Amino Acids and Amines by Chromatography: Methods and Protocols is intended to serve as a ready-to-use guide for the identification and quantification of amino acids and amines in various matrices, providing an overview on the theory and protocol of available methods. It presents chromatograms with exact elution programs enabling visual analysis and compares the advantages-disadvantages of various chromatographic techniques. In accordance with the chronological order of the development of chromatographic methods, different techniques are discussed: The possibilities of gas chromatography (GC), followed by those of the high performance liquid chromatography (HPLC) and the most recent techniques capillary electrophoresis (CE), capillary, electrochromatography (CEC). The characteristics of the given chromatographic procedure, relating to the topic in question, are classified according to the preliminary preparation/derivatization process(es), which means the simple methods, suitable for the analysis of the selected compound(s) in natural form, are followed by various derivatization proposals. Detailed protocols provide the reader with guidance in beginning tasks and on how to improve current methods. This book appeals to a wide audience and is recommended for those looking towards the wider reaches of identification and quantification of amino acids and amines. * Provides a systematic, and comprehensive summary of chromatographic techniques and derivatization processes * Compares advantages/disadvantages of various chromatographic techniques * Readers can undertake practical tasks using detailed protocols given in the book

HPLC and CE: Principles and Practice presents the latest information on the most powerful separation techniques available: high-performance liquid chromatography (HPLC) and capillary electrophoresis (CE). Fundamental theory, instrumentation, modes of operation, and optimization of separations are presented in a concise, non-technical style to help the user in choosing the appropriate technique quickly and accurately. Well- illustrated and containing convenientend-of-chapter summaries of the major concepts, the book provides in-depth coverage of trouble-shooting, improvement of resolution, data manipulation, selectivity, and sensitivity. Graduate students, technicians, and researchers who must use separations with little or no background in analytical chemistry can overcome separation anxiety and get started in obtaining the best possible separations in minimal time. The book will alsobe useful to analytical chemists who need a better understanding of theory and processes. Key Features * Fully up-to-date information on both HPLC and CE includes troubleshooting and comparisons of the two techniques * Applicable to a wide variety of separation problems * Covers basic concepts governing any separation as well as instrumentation and how to use it * Helps the user to obtain optimal resolution in minimal time * Contains information on special procedures such as chiral separations, affinity chromatography, and sample preparation * Includes information on upcoming trends such as miniaturization * Major concepts in each chapter are organized to allow access to information easily and quickly * Contains practical bibliography for accessing the literature
