“…The rats were fasted for 1 day before the experiments and were anesthetized using diethyl ether. EEP-SPD, the physical mixture of EEP-SPD/Stevia-G (1/10 w/w), and propolis/Stevia-G (1/10) were orally administered (50 mg/kg solid content of propolis) using an oral dosing syringe after dispersion in 50% propylene glycol as reported by Konishi et al [17]. Blood samples (600 μl) were taken from the jugular vein at 10, 20, 30, 45, 60, 120 and 240 min after administration.…”
