Eriodictyol a plant flavonoid attenuates LPS‑induced

Eriodictyol a flavonoid found in citrus fruits has been reported to have a potential antioxidative and anti-inflammatory activity in vitro (34 42) In the present study it was demonstrated that eriodictyol could attenuate the LPS-induced ALI in mice thus prolonging their survival time as well as that eriodictyol treatment could protect

Sarcocephalus latifolius is used as a traditional medicine for curing many diseases in Sudan The main objective of the current study was to determine the antioxidant activity and acetylcholinesterase inhibition (AChEI) of S latifolius and to estimate its total phenolic and flavonoid contents Antioxidant activity of the tested plant extracts was carried out by determining their ability to

polyphenol pharmacokinetics antioxidant capacity neurodegenerative disorders brain damage pharmacognosy The basic chemistry of Flavonoids Flavonoids are polyphenolic plant secondary metabolites which are biosynthesized from a polyketide chain and a phenylpyruvic moiety which may either come from shikimate or amino-acid metabolism [1 2 3]

The ability of various natural flavonoid structures to inhibit aromatase activity in vitro has been documented previously in human placental microsomes (Ibrahim and Abul-Hajj 1990 Kellis and Vickery 1984 Le Bail et al 1998) in human preadipocytes (Campbell and Kurzer 1993) in JEG-3 human placental choriocarcinoma cells (Saarinen et al

2002-10-1The flavonoid heterocycle contributes to antioxidant activity by (i) the presence of a free 3-OH and (ii) permitting conjugation between the aromatic rings The closed C-ring itself may not be critical to the activity of flavonoids given that chalcones are active antioxidants [97]

The antioxidant activity and biological properties of these phenolic metabolites have been poorly assessed but it has been shown that phenylacetic acids possess anticarcinogenic activities (Samid and others 1997 Thibout and others 1999) and diHPA or 4‐HPA were more effective than their precursors (rutin and quercetin) inhibiting in vitro
