Antioxidant and free radical scavenging activities of some medicinal plants from the Lamiaceae

Pedalium murex Linn (Pedaliaceae) fruits: a comparative antioxidant activity of its different fractions

“…Recently, interest has increased considerably in finding naturally occurring antioxidants for use in foods or medicinal materials to replace synthetic antioxidants [6] . It has been demonstrated that plants, containing high amounts of secondary metabolites like phenolic have been identified as a free radical or active oxygen scavengers and can prevent damages caused by oxidative stress [19][20][21] . Increasing experimental evidence has suggested that these compounds can affect a wide range of cell biological functions by virtue of their radical scavenging properties [6] .…”

Biochemical changes in phenols, flavonoids, tannins, vitamin E, β–carotene and antioxidant activity during soaking of three white sorghum varieties

“…Total phenols were determined colorimetrically as described by Matkowshi and Piotrowska [23] . Sample (1 g) was mixed with 10 mL 80% methanol in a dark bottle and shaking for 2 h. The color was developed by Folin-Ciocalteu reagent and sodium carbonate.…”

Effects of extracts from Italian medicinal plants on planktonic growth, biofilm formation and adherence of methicillin-resistant Staphylococcus aureus

“…Previous studies have demonstrated that white horehound extracts exhibit antispasmodic (Schlemper et al, 1996), antioxidant (Berrougui et al, 2006;Matkowski and Piotrowska, 2006;Weel et al, 1999), hypotensive (El Bardai et al, 2001), insecticidal (Pavela, 2004), and analgesic (Meyre-Silva et al, 2005) properties. Marrubium species are rich in diterpenes, caffeic acid derivatives, sterols, and flavonoids (Khanavi et al, 2005;Lazari et al, 1999).…”
