Precise quantification of quercetin across different matrices is essential for leveraging its health-related potential. This review synthesizes quercetin sample preparation and determination strategies, comparing advantages and limitations while covering recent developments and emphasizing pharmaceutical and biological applications.","cbCaioIy7gF8SoYj","https://ap.wps.com/l/cbCaioIy7gF8SoYj","pdf",3484194,1,27,"English","en","# Introduction\n## Quercetin and quercetin glycosides background\n# Analytical determination methods (review scope)\n## Spectroscopic approaches\n## Chromatographic approaches\n## Electrophoretic approaches\n## Electrochemical approaches","[{\"question\":\"Why is accurate determination of quercetin important?\",\"answer\":\"Accurate determination supports evaluation of quercetin’s potential health benefits.
