Abstract

Glyphosate [N-(phosphonomethyl)glycine] was separated from its potential metabolites, aminomethylphosphonic acid, glycine, and sarcosine by using 500 μm-thick cellulose plates developed with ethanol:water:15 N NH4OH:trichloroacetic acid (TCA):17 N acetic acid (55:35: 2.5:3.5 g:2, v/v/v/w/v with v in ml). This TLC system separated impurities from the 14C-glyphosate standard and glyphosate from possible metabolites in treated field bindweed (Convolvulus arvensis L.).
