Excerpt

This study assessed the absolute and relative bioavailabilities of dodeca-2E,4E,8E,10E/Z-tetraenoic acid isobutylamides (tetraene), one of the main bioactive constituents in Echinacea, administered as pure compounds or as an Echinacea purpurea root extract preparation. Ten rats received 0.75 mg/kg dodeca-2E,4E,8E,10E/Z-tetraenoic acid isobutylamides oral, pure and within 158.6 mg/kg Echinacea purpurea extract, or intravenous.[...]
