TLDR
Chromatographic investigation of a methanolic extract of white lupin roots has revealed the presence of six new dihydrofurano-and pyrano-substituted isoflavones in roots and leaves of L. albus, presumed to be the precursor of lupisoflavone.Citations

Journal ArticleDOI
In vitro scavenger activity of some flavonoids and melanins against O2
TL;DR: It is shown that the presence of hydroxyl groups in the B ring of flavonoids is essential for their scavenger activity, and the existence of a hydroxYL at C-3 enhances the scavenger ability of Flavonoids.
