Abstract

Olive oil contains many different compounds which are responsible for its nutritional and sensorial value. However, some compounds present in olive oil at very low amounts have not yet been identified. Here, the detection of tetrahydrogeranylgeraniol and dihydrogeranylgeraniol, in both the total aliphatic alcohol and waxy fractions of extra virgin olive oil, is reported for the first time using GC and GC-MS methodologies. It was suggested that tetrahydrogeranylgeraniol and dihydrogeranylgeraniol do not originate from the hydrolysis of the chlorophyll but are present as diterpenic esters.
