New Genera of Flavonols and Flavonol Derivatives As Therapeutic Molecules
Journal of the Korean Society for Applied Biological Chemistry, 2011Natural products from plants and microorganisms traditionally have provided the pharmaceutical industry with one of the most important sources of “lead” compounds in the search for new drugs and medicines. The diversity of polyphenol structure is enormous.

Antioxidant flavonol glycosides from Dorycnium hirsutum
Chemistry of Natural Compounds, 2006Seven flavonol glycosides were isolated and identified from the aerial parts of Dorycnium hirsutum, together with catechin, D-pinitol, β-sitosterol, and stearic acid. The extracts and the isolated flavonol glycosides were evaluated for their antioxidant activity, using the DPPH test (radical scavenging) and the lipoxygenase assay (lipid peroxidation).
