Aldaric, quinic and hexosides derivatives of p-coumaric, ferulic and sinapic acids
were quantified by the curves of the corresponding free acids; (+)-catechin-hexoside and (+)-catechin-acylhexoside based on the curve of (+)-catechin; flavonols, derivatives of kaempferol, quercetin and isorhamnetin by the curves of kaempferol-3-O-glucoside, quercetin-3-O-glucoside and isorhamnetin 3-O-rutinoside,
respectively. Flavanones, eridictyol derivatives based on the curve
of narigenin; and naringenin and hesperetin derivatives as
naringenin and hesperitin, respectively. Results were expressed
as lg of phenolic compound/g of extract.
