Silica Gel Column Chromatography PowerPoint PPT Presentations

The segments of plants that have medicinal value and mending properties are called as bioactive compounds and they experience a progression of the procedure called as Extraction, Isolation, and Characterization. Column Chromatography strategy for plant removes is one such method for confining and distinguishing the bioactive compounds utilizing a stationary stage, for example, Silica gel or Alumina. The Development of logical strategies needs to prompt a subjective and in addition quantitative examination of Isolation of bioactive compounds from Plants which are herbs with a muddled arrangement of blends framed through different pathways.

• Chromatography has been a fundamental technique used for chemical separation. Specifically, column chromatography, typically taught in introductory organic chemistry laboratories. This situation runs contrary to the principles of responsible chemical and waste management emphasized by the green chemistry movement. • Chromatographic techniques have significant role in natural products chemistry as well as contribute dramatically in the discovery of novel and innovative compounds of pharmaceutical and biomedical importance. • This study focused on step-by-step visual demonstration of fractionation and isolation of biologically active plant secondary metabolites using column-chromatographic techniques.
