Absorption, Metabolism, and Excretion by Freely Moving Rats of 3,4-DHPEA-EDA and Related Polyphenols from Olive Fruits (Olea europaea)

Figure 1

Metabolites from 3,4-DHPEA-EDA (a), hydroxytyrosol (b), and oleuropein (c) in plasma from the portal vein over time after oral administration (300 mg/kg for 3,4-DHPEA-EDA, 100 mg/kg for HT, and 300 mg/kg for Ole). Values of means and SEM are from measurements performed in triplicate. Sampling times are described in the text. HT: hydroxytyrosol, Ole: oleuropein, HVA: homovanillic acid, and HVAOH: homovanillyl alcohol.
