“…Some biological and therapeutic effects have been reported for the plant such as antioxidant (Esmaeili et al, 2009;Ardestani et al, 2008), antiinflammatory (Tariq et al, 1989;Capasso et al, 1983), antinociceptive (Baluchnejadmojarad et al, 2005;Abdollahi et al, 2003), antipyretic (Aggelis et al, 1998;Autore et al, 1984), anti-microbial (Autore et al, 1984), hypolipidemic (Rasekh et al, 2001), hepatopro-tective (Panovska et al, 2007), cytotoxic and apoptotic effects (Rajabalian et al, 2008). The plant poses complex chemical composition with presence of new clerodane type diterpenes (Malakov and Papanov, 1983;Marquez and Valverde, 1979), essential oil with dominating sesquiterpene alcohols and pinenes (Cozzani et al, 2005;Moghtader, 2009;Kabouche et al, 2007), phenylethanoid glycosides such as verbascoside and poliumoside (Oganesyan et al,1991), flavone glycosides with highly methylated aglycons (Verykokidou-Vitsaropoulou and Vajias, 1986;Rizk et al, 1986;Kawashty et al, 1999;Harborne et al, 1986;Sharififar et al, 2009), etc. Flavonoids are representing the most important group of active components of Teucrium species, and many of the activities of these plants are attributed to the flavonoid class of secondary metabolites. It is also well known that the composition and the content of the flavonoids in plant material could be variable depending of the season, location and environmental condition of plant growth as well as the influence of other different factors (Liu et al, 1994;De Castro, et al, 2006;Bagdonaite et al, 2009).…”
