代谢
拟除虫菊酯在体内被广泛代谢,粪便和尿液中母体化合物的残留物仅占10%。已鉴定出六种代谢物,并提出了两种主要的代谢途径,第一种涉及双键和/或甲基基团的氧化,第二种涉及酯键的水解。拟除虫菊酯I主要通过氧化过程代谢,而拟除虫菊酯II则通过水解和氧化过程的结合进行代谢。
Pyrethrins are extensively metabolized, the residues of the parent compound in feces and urine representing only 10%. Six metabolites were identified and two major metabolic pathways were suggested, the first involving oxidation of the double-bond and/or the methyl groups and the second involving hydrolysis of the ester bond. Pyrethrins I are metabolized mainly through oxidative processes, while pyrethrins II are metabolized through a combination of hydrolytic and oxidative processes.
