UHPLC results on GCWat containing fractions from different recovery studies. In the chromatograms, (a) represents the reference standard sample and (b) the GCWat containing fraction. The GCWat containing fractions A, B, C, and D were recovered from rutin-GCWat solution, quercetin-GCWat solution, kaempferol-GCWat, and daidzein-GCWat solution, respectively.
