In a recent study, several acylated glycosylated flavonols were identified in green tea composition but in low concentration (around 0.36 mg/g) compared with flavanols. These compounds presented kaempferol as the basic structure, with acetyl and p-coumaryl moieties linked to hexosyl and hamnosyl structures forming compounds as kaempferol 3-O-p-coumaroylglucoside and kaempferol 3O-p-coumaroyldirhamnosylhexoside [23].
