Plectranthus esculentus (Lamiaceae)tubers in Jos, Nigeria produced a white starch. This starch was characterized by the application of Fourier Transform Infrared (FTIR) and 1-Dimensional (ID) Nuclear Magnetic Resonances (NMR) spectroscopy. Application of FTIR and ID-NMR spectroscopy to the original starch from P.esculentus tubers in combination with chemical data, led to confirm that the structure of the original polysaccharide contains α-D-glucose linked at 1 → 4. It was demonstrated that ID-NMR spectroscopy is a good tool for structural information of complex hetero-polysaccharides.
