Specificity
The specificity of the developed method for the analysis of Eupalitin
3-O- β-D-galactopyranoside in the extracts was ascertained by analysis
of standard and sample. The six tested polyphenols in samples were
confirmed by comparing the Rf value and spectra of the
spot with that of the standard. The peak purity of individual compounds
was assessed by analyzing the spectra at peak start, peak apex, and peak
end positions of the band.
