In this study the correlation of phytochemical characteristics and antioxidative properties of classical herbal tea extracts - Infusum solidaginis, Decoctum solidaginis, Maceratum solidaginis - and tinctures prepared by various concentration of ethanol (40, 70, 96% v/v) have been examined for the release of flavonoids and their antioxidant activity. Quantitative and composition determination of flavonoids were carried out by spectrophotometry, high-performance liquid chromatography and capillary electrophoresis, respectively. Hydrogen-donating ability and reducing power properties were used to define in vitro radical scavenging activity of Solidago extracts, but integral antioxidative capacity was determined by luminometry (Photochem®), calculating the ascorbic acid equivalents. Chlorogenic acid, quercetin-3-O-β-D-rutinoside, quercetin-3-O-β-D-galactoside, quercetin-3-O-β-D-glucoside, quercetin-3-O-β-D-rhamnoside, kaempferol-3-O-α-L-rhamnoside and quercetin were confirmed by retention times and UV spectra. Based on the dissolution rate, variance of flavonoid release and ascorbic acid equivalents it was concluded, that Tinctura solidaginis (70% v/v ethanol) and Infusum solidaginis are the most appropriate preparations.
