Vergleichende tierexperimentelle Untersuchungen mit Kaffee und Tee

1969

14C-Coffein wurde an Ratten als Coffeinlosung bzw. als Bestandteil eines Kaffee-oder Tee-Infuses per os verabreicht. Die Resorption von Coffein erfolgte nach Verabreichung von Coffeinlosung und Kaffee-Infus verhaltnismasg schnell, nach Verabreichung von Tee-Infus dagegen mit einer gewissen Verzogerung. Die14C-Aktivitatswerte im Serum und im Rattenkorper fielen nach Erreichung ihres Maximums nach Gabe von Coffein und Kaffee sehr schnell, nach Gabe von Tee dagegen sehr langsam ab. Die14C-Ausscheidung im Harn war nach Verabreichung von Tee deutlich geringer als nach Coffein oder Kaffee.
