Research output: Chapter in Book/Report/Conference proceedingConference contribution


The analyses of citrus flavonoids have been progressed well in recent years due to accelerated and fruitful research in the field of biological activity and health beneficial effects of compounds from citrus genus, particularly methylated flavonoids from citrus peels, such as polymethoxyflavones (PMFs) and 5-hydroxylated polymethoxyflavones (5-OHPMFs). Recent research results and broad application of PMFs and 5-OHPMFs in the areas of nutraceuticals, pharmaceuticals, and functional foods have prompted the identification and quantification of these flavonoids, which serves the basis of characterization and is of great significance. This chapter summarizes the development of characterization of PMFs and 5-OHPMFs from random study to systematic identification to validated and accurate measurement in citrus peels and other matrices containing methylated flavones.
