Abstract

Abstract Isopropyl-3-chlorocarbanilate-phenyl UL- 14C (CIPC- 14C) is absorbed, translocated and metabolized by soybean plants. Water-soluble metabolites in root and shoot were purified and the root major metabolite characterized. The acetylated aglucones from the β-glucosidase hydrolysis and the esters from the direct acetylation of CIPC- 14C polar metabolites were purified by GLC and analysed by mass spectrometry. The data showed that the phenyl riong of CIPC- 14C was hydroxylated by both root and shoot tissues. Isopropyl-5-chloro-2-hydroxycarbanilate (hydroxy-CIPC) was the predominant aglucone liberated by β-glucosidase from polar metabolites in root and shoot. The o-glucoside of hydroxy-CIPC was shown to be present, by direct acetylation and characterization. In shoot tissue the major metabolites were dechlorinated hydroxy-CIPC and were not hydrolysed by β-glucosidase. These data show that soybean root or shoot tissues hydroxylate the phenyl ring of CIPC- 14C but do not alter either the isopropyl alcohol moiety or the earbamate bond.
