Chromatogram of the separation of flavonoids in methanol extract from L. album subsp. album flowers with the multiple gradient development technique (MGD). The bands of the standards correspond with the bands of the compounds in the extract: 1—rutoside; 2—isoquercetin; 3—quercetin; A—ethyl acetate extract-excluded from the investigations; B—methanol extract. Visible light, derivatization with the use of a 1% methanolic solution of aluminum chloride. The mobile phase elution program is given in Table 2. Chromatographic plate HPTLC Si 60 F 254.
