The antioxidant effect of aqueous methanolic herb extracts of Serratula coronata, S. wolffii and S. tinctoria was investigated using both enzyme-dependent and enzyme-independent systems. The extracts displayed concentration-dependent inhibition of lipid peroxidation. Flavonoids and ecdysteroids
The simultaneous determination of 20-hydroxyecdysone ( 1), 25-deoxy-11,20-dihydroxyecdysone ( 2), kaempferol 4',7-dimethyl ether ( 3) and biochanin A ( 4) in the fruit, leaf and root of Serratula strangulata Iljin has been investigated by micellar electrokinetic capillary chromatography for the
Extracts from wool dyed with sawwort (Serratula tinctoria L.) obtained with methanol/formic acid and methanol/hydrochloric acid solutions were examined by high-performance liquid chromatography with UV detection coupled with electrospray ionization tandem mass spectrometry. Chromatograms and mass
Numerous ecdysteroids are isolated from the herb of Serratula wolffii Andrae, a cultivated plant. The isolation procedure includes a variety of low-pressure liquid chromatography, thin-layer chromatography (TLC), gel chromatography, and high-performance liquid chromatography (HPLC) methods. The
