Effect of Egyptian Propolis on the Susceptibility of LDL to Oxidative Modification and its Antiviral Activity with Special Emphasis on Chemical Composition
Z Naturforsch, 2007 Sep-Oct;62(9-10):645-55
The antioxidant activity of eight Egyptian propolis samples from different localities was evaluated by the antioxidative potential and capacity ofthe DPPH-ESR signal, superoxide anion generated in the xanthine-xanthine oxidase (XOD) system and low density lipoprotein (LDL) peroxidation assay…
The antiviral activity ofpropolis samples was investigated. They showed variations in their activity; sample D induced the highest antiviral activity against Newcastle disease virus and infectious bursal disease virus.
42 Polyphenolic compounds were identified by HPLC; 13 aromatic acids, esters and alcohols were present, 29 flavonoids were identified, 6 of them being new to propolis.
