Examination of extracts from seeds and foliage of several species known to contain fluoroacetate, using 13F NMR spectroscopy, has shown the presence of the characteristic FCH2-signal in most of them and enabled quantitative determination of their fluoroacetate content. No other fluorine-containing plant metabolites were detected; fluoroacetate was not detected in the extracts of several non-toxic species. The limit of detection is estimated to be ca 4 μg/g. © 1987.
