Olive fruits showed greater accumulation of hydroxytyrosol and p-hydroxybenzoic acid in plants on which AM was inoculated when compared to the values of uninoculated plants. AMF inoculation resulted in a reduction in vanillin, dimethyloleuropein and luteolin content of olive fruits. Secoiridoid aglycones in the olive oils from treated trees generally tend to decrease. There were differences in the levels of phenolics in fruits and their corresponding oils, such as the amount of hydroxytyrosol rose in AMF+ MC applied fruits, nevertheless the amount of verbascoside, a secoiridoid conjugate of hydroxytyrosol, declined in the oil of AMF+ MC treated plants. After the application of AMF + MC, the oils did not show a significant change in the total phenolics content contrarily to olive fruits. These results highlight that phenolic compounds having hydrophilic structure were influenced by AMF+ MC application more than those of lipophilic structure. (C) 2015 Elsevier B.V.
