Abstract
This study describes the use of liposomes as biological membrane models to evaluate
the potential of natural antioxidants as inhibitors of lipid peroxidation. Antioxidative
effects of by-products from the pomegranate juice industry, i.e., pomegranate peel
(PPE) and seeds extracts (PSE) and combined antioxidative effects of PPE or PSE with
a-tocopherol (TOH), quercetin (QC) and ascorbic acid (AA) on peroxidation of L-aphosphatidylcholine
liposomes as initiated by lipophilic or hydrophilic azo-initiators
were investigated. Extracts from PPE and PSE had an antioxidative effect as evidenced
by a lag phase for formation of phosphatidylcholine-derived conjugated dienes. A combination
of TOH or QC with PPE or PSE respectively, showed synergism in prolonging
of the lag phase. Thus, the results of the present study show the possibility of utilising waste PPE or PSE
