Distribution of p-coumaroylquinic acids in commercial Coffea spp. of different geographical origin and in other wild coffee species
Quantitative analyses of mono-p-coumaroylquinic acids (pCoQAs) and total chlorogenic acids (CGAs) in green coffee commercial lots of C. arabica, C. canephora and C. liberica from different geographical origins and eight wild Coffea species were carried out. Among the commercial lots, pCoQAs averag...

| Sumario: | Quantitative analyses of mono-p-coumaroylquinic acids (pCoQAs) and total chlorogenic acids (CGAs) in green
coffee commercial lots of C. arabica, C. canephora and C. liberica from different geographical origins and eight
wild Coffea species were carried out. Among the commercial lots, pCoQAs average content of C. arabica
(0.67 mg/g) is higher than that of C. canephora (0.40 mg/g) being C. liberica intermediate (0.58 mg/g). As far as
the analyzed wild Coffea species is concerned, C. pseudozanguebariae is characterized by the lower pCoQAs
content (0.12 mg/g) whereas C. sessiliflora is by far the richest source of pCoQAs (2.18 mg/g). Effect of the
roasting process on the mono-p-coumaroylquinic acids profile was evaluated for the economically exploited
species C. arabica and C. canephora. For the first time distribution of mono-p-coumaroylquinic acid isomers in
wild coffee species by fast and accurate UHPLC-DAD analyses using authentic standards previously synthetized,
is reported. |
