Table 1.
Concentration of phenolic compounds, triterpenic acids and sugars (g/kg) in the olive leaf samples from 4 different orchards. Data are expressed as the mean values of duplicates. Standard deviation is in parenthesis. “Others” is the sum of hydroxytyrosol 4-glucoside, hydroxytyrosol 1-glucoside, tyrosol, caffeic acid, verbascoside, ligustroside and luteolin 7-glucoside.
