Phenolic components of Olea europea: Isolation of new tyrosol and hydroxytyrosol derivatives

Two new phenolic compounds were isolated from fruits of Olea europaea, Hojiblanca cultivar. The first compound is the methyl acetal of the aglycone of ligstroside, while the second derivative, not yet reported in the literature, is the b-hydroxytyrosyl ester of methyl malate. These microcomponents may be responsible for hedonistic-sensorial characteristics of olive products
