APPLICATIONS OF ELECTRON PARAMAGNETIC RESONANCE SPECTROSCOPY IN NATURAL PRODUCT RESEARCH

Abstract

Background Applications of electron paramagnetic resonance (EPR) spectroscopy to natural product research have proven useful to understand the properties of natural product extracts and their intrinsic compounds. There are few reviews on this subject written as an initial introduction. Aims To provide an explanatory review of applications of EPR to natural products research. Methods The search for this review was carried out in the following databases: SciFinder, Google Scholar, PubMed, MEDLINE, and Science Direct, with particular emphasis on publications from the last decade. Results The articles chosen showed qualitative and quantitative data about the applications of EPR in the natural product research area. Studies include the use to measure radical scavenging capacity and direct detection of radicals in extracts. Other applications include the study of autooxidation, and photochemical properties. Conclusion This review brings together many examples highlighting methods by which EPR spectroscopy is useful in natural products research as a guide for future use
