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

Figure 3

Monitoring of metabolites in urine and bile after oral and intravenous administration of 3,4-DHPEA-EDA, hydroxytyrosol, and oleuropein. Excretion rates are expressed as excretion/dose ratios. EDA: 3,4-DHPEA-EDA, HT: hydroxytyrosol, Ole: oleuropein, HVA: homovanillic acid, and HVAOH: homovanillyl alcohol.
