a
All the monoglycosylated myricetins and quercetins were expressed as the molar equivalent of myricetin, 3-O-rhamnoside, and quercetin 3-O-glucoside, at 350 nm, respectively.
b
All the monoglycosylated myricetins and quercetins were expressed as the molar equivalent of myricetin, 3-O-rhamnoside, and quercetin 3-O-glucoside, at 350 nm, respectively.
c
Calculated as the molar equivalent of cyanidin 3-O-glucoside based on its vis peak absorption at 520 nm.
d
