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 present in the extracts were evaluated as antioxidant components. The flavonoid-containing fraction of the...
Three new flavonoid glycosides (1–3) and nineteen known compounds (4–22) were isolated from the aqueous ethanolic extract of the seed of Oroxylum indicum. The structures of 1–3 were elucidated on the basis of spectroscopic analysis. Antioxidant activities of all the isolated compounds were evaluated using a DPPH and an ORAC assay. Compounds 3, 5–7, 9 and 12 exhibited potent antioxidant activity in...
