Abstract

This chapter is focused on the main (S)-2-phenylchroman-4-one derivatives, especially hydroxyl- and methoxy substituted compounds (flavanone aglycones), as well as flavanone glycosides. The first part presents the chemistry and functionality of flavanones that have been widely found in various plants and food products. It is the case of hesperetin, naringenin, and isosakuranetin, including their glycosides (hesperidin and naringin) from Citrus species, as well as liquiritigenin in Glycyrrhiza species (licorice). However, flavanone glycosides are more concentrated in these natural sources, and other glycosylated derivatives can be found, e.g., neohesperidin, didymin, prunin, or narirutin in Citrus. Antioxidant mechanisms of flavanone have been presented and discussed related to quantum-chemical descriptors obtained by molecular modeling. The hydrophobicity of flavanones glycosides well correlates with the incidence of hydroxyl/methoxy groups and with sugar units. The presence of mono- and disaccharide moieties in flavanone glycosides increases the hydrophilicity, and thus, the water solubility/bioavailability. As a consequence, the metabolism of flavanones in various organs of the human body is described in the second part. The general biosynthetic pathways of flavanones in plants, particularly of sakuranetin in rice, (2S)-pinocembrin in engineered Escherichia coli or E. coli co-culture, homoeriodictyol by recombinant flavone 3’-O-methyltransferase, and hesperetin from hesperidin in Citrus juice, are also discussed in this part. The final section is dedicated to the occurrence, separation/production, analysis, and applications of specific flavanone aglycones and glycosides as food ingredients. Special attention has been given to butin, eriodictyol, homoeriodictyol, hesperetin, liquiritigenin, naringenin, pinocembrin, and sakuranetin from flavanone aglycone class. On the other hand, hesperidin, neohesperidin, naringin, narirutin, eriocitrin, neoeriocitrin, poncirin, neoponcirin, didymin, prunin, and sakuranin are known to be the main flavanone glycosides, which have been discussed in this section. The chapter ends with conclusion and future perspectives related to this important class of flavonoids with valuable biological and food applications.
