In vitro biotransformation of flavonoids by rat liver microsomes
TL;DR: Sixteen naturally occurring flavonoids were investigated as substrates for cytochrome P450 in uninduced and Aroclor 1254-induced rat liver microsomes and results indicate that demethylation only occurs in the B-ring when the methoxy group is positioned at C4', and not at the C3'-position.

Potent anti-inflammatory activities of hydroalcoholic extract from aerial parts of Stachys inflata on rats
Nasim Maleki,Alireza Garjani,Hossein Nazemiyeh,N. Nilfouroushan,A.T. Eftekhar Sadat,Z. Allameh,N. Hasannia +6 more
TL;DR: The anti-inflammatory properties of total methanol extract isolated from aerial parts of Stachys inflata were investigated in two well-characterised inflammatory models in rats, carrageenan-induced rat paw oedema and formalin-induced paw licking.
1 H nuclear magnetic resonance spectroscopy of flavonoids and their glycosides in hexadeuterodimethylsulfoxide
K.R. Markham,H. Geiger +1 more
TL;DR: The use of CCl4-soluble trimethyl-silyl derivatives for lH nuclear magnetic resonance (NMR) spectroscopy has been well documented (Mabry et al. 1970, Markham and Mabry, 1975; Markham, 1982), but in recent years the use of these derivatives has largely superseded.

Extraction and identification of natural antioxidant from the seeds of the Moringa oleifera tree variety of Malawi
Stavros Lalas,John Tsaknis +1 more
TL;DR: In this paper, a mixture of chloroform/methanol (50∶50) was used to extract the sunflower oil from the dried seeds of the Moringa oleifera tree (variety of Malawi) and the induction period measurements demonstrated a great resistance to oxidative rancidity.

Three flavonoid glycosides containing acetylated allose from stachys recta
TL;DR: Three flavone glycosides, obtained from Stachys recta, were identified as 4′- O -methylisoscutellarein, isoscutelarein and 3′-hydroxy-4′-O - methylisosCutellare in, isolated for the first time.
