3,4-DIHYDROXYPHENYLGLYCOL, A MAJOR C-6-C-2 PHENOLIC IN OLEA-EUROPAEA FRUITS

The major C-6-C-2 phenolic compounds found in the vegetation water of fruits of Olea europaea, Dritta and Cipressino cultivars were 4-hydroxyphenylethanol, 3, 4-dihydroxyphenylethanol and 3,4-dihydroxyphenylglycol. The latter, a formal metabolite of norepinephrine, is first reported as a major component of the olive phenolic fraction. The composition of sugars and polyols present in vegetation water is also reported.
