Abstract
The unique aromatic peptide 4-(
p
-aminobenzoylamino)-2-aminobenzoic acid, carotamine, together with 2,4-diaminobenzoic acid, isolated for the first time from a plant source, were identified from the aqueous alcoholic extract of the aerial parts of
Daucus carota
L. var. boissieri (Apiaceae). The structures were determined through conventional methods of analysis and confirmed by LC-ESI/MS and NMR spectral analysis.
