Tropital 
When tropital was fed to mice, rats or hamsters, degradation occurred 
primarily at the side chain with excretion of metabolites in the urine. 
Some metabolism of the methylene dioxide to CO, also occurred. The glycine 
and glucuronate conjugates were found (755). 
Rats, mice and rabbits, administered tropital orally, metabolized the 
tropital to piperonal, piperonylic acid, N-piperonylglycine and two un- 
identified acid compounds. When piperonylic acid was fed to mice, both 
the free acid and glycine conjugate were observed (755). 
After incubation of tropital with mouse liver microsomes and NADPH), 
tropital was degraded to piperonylic acid via piperonal (755).
