Inhibitory Activity of Minor Polyphenolic and Nonpolyphenolic Constituents of Olive Oil AgainstIn VitroLow-Density Lipoprotein Oxidation

The minor polyphenolic and nonpolyphenolic constituents of olive oil were examined, in various doses, against copper ion-induced low-density lipoprotein (LDL) oxidation and were found, in optimal doses (final concentration, 10 microM or 20 microM), to have remarkable biological activity, contributing to that previously reported for the major phenolic compounds. The main phytosterols, beta-sitosterol, campesterol, and stigmasterol, were found to...
