Chromatography , Preparative, Analytical, Isolation , PurificationAbstract
This review aims to identify the most appropriate approaches to method selection and optimization challenges encountered in the isolation and purification of bioactive compounds from food, natural products, and pharmaceutical matrices using various chromatographic techniques (both analytical and preparative). A comparative evaluation is presented of the fundamental principles, application areas, and advantages of analytical and preparative chromatography, including techniques such as thin-layer chromatography, liquid-liquid chromatography, counter-current chromatography (CCC), and high-performance liquid chromatography, in both their analytical and preparative variants. These techniques are examined based on critical parameters including instrumentation components, efficiency, purity levels, scalability, and cost-effectiveness. It is highlighted that preparative techniques offer advantages such as the ability to obtain compounds of high purity, reduced solvent consumption, and ease of scalability, while analytical techniques are primarily preferred for qualitative and quantitative analyses. This review provides a holistic perspective on the interdisciplinary applications and technical distinctions of chromatographic separation technologies. The combined evaluation of analytical and preparative approaches is expected to contribute significantly to method selection and optimization, particularly in food analysis and compound isolation processes.
