The metabolism and disposition of 14C-labelled 2,2',4,4',5-pentabromodiphenyl ether (BDE99) were studied in F344 rats and B6C3F1 mice. Approximately 85% of a 1 micromol kg-1 oral dose was absorbed by male rats and mice. Within 24 h following oral dos

Pulegone is a monoterpene ketone that is usually associated with the herb pennyroyal but is also found in the essential oils from many other mint species. It is the major constituent of pennyroyal oil. Pennyroyal is used as a flavoring and fragrance

The disposition of [ 14 C]-labeled n -butyl glycidyl ether (BGE, 3-butoxy-1,2-epoxypropane) was studied in rats and mice. The majority of a single p.o. dose (2–200 mg/kg) was excreted in urine (rats, 84–92%; mice, 64–73%) within 24 h. The rest

The disposition of the 14C-labelled polybrominated diphenyl ether (PBDE) 2,2',4,4',5,5'-hexaBDE (BDE153) was investigated in rodents following single and multiple doses and in a mixture with radiolabelled 2,2',4,4'-tetraBDE (BDE47) and 2,2',4,4',5-pe

The metabolism and disposition of 14C-labelled juglone in male F344 rats following oral, intravenous and dermal administration were studied. Approximately 40-50% of an oral dose (0.1 to 10 mg kg-1) and less than 20% of the dermal dose (4 mg kg-1) wer

(R)-(+)-Menthofuran is a metabolite of (R)-(+)-pulegone, the chief constituent of pennyroyal oil. Menthofuran has been shown to account for a significant percentage of pulegone toxicity through further metabolism to a reactive intermediate, an enonal

(R)-(+)-Pulegone, a monoterpene ketone, is a major component of pennyroyal oil. Ingestion of high doses of pennyroyal oil has caused severe toxicity and occasionally death. Studies have shown that metabolites of pulegone were responsible for the toxi
