The HPLC/DAD Fingerprints and Chemometric Analysis of Flavonoid Extracts from the Selected Sage (Salvia) Species
Figure 2
(a) A comparison of the HPLC/DAD fingerprints for the five different sage species (S. nemorosa, S. forskahlei, S. azurea, S. amplexicaulis, and S. officinalis). The chromatograms were registered at the wavelength = 254 nm. All fingerprints except for S. officinalis are those with the highest sums of the separated chromatographic peak areas. (b) A comparison of the HPLC/DAD fingerprints for the five different sage species (S. glutinosa. S. pratensis ssp. Haematodes. S. staminea. S. triloba., and S. officinalis). The chromatograms were registered at the wavelength = 254 nm. All fingerprints except for S. officinalis are those with the highest overall sums of flavonoids, as spectrophotometrically established.
