polysaccharides; antioxidant activity
Eleven polysaccharides have been isolated from the leaves of Arctium lappa var. herkules, Aloe barbadensis, Althaea officinalis var. robusta, Plantago lanceolata var. libor, aerial parts and roots of Rudbeckia fulgida var. sullivantii, stems of Mahonia aquifolium, and peach-tree (Prunus persica) gum exudates. The polysaccharides were investigated for their ability to inhibit peroxidation of soyabean lecithin liposomes by OH radicals. The highest inhibition was found with glucuronoxylans of A. officinalis var. robusta and P. lanceolata var. libor, aerial parts. Their antioxidant activity accounted for similar to 69% of the activity of the reference compound a-tocopherol. The activity of eight polysaccharides ranged from 20 to 45%, while the fructofuranan from P lanceolata var. libor roots was practically inactive. (c) 2006 Elsevier B.V. All rights reserved.
