文摘

Genotypic variation of cowpea seeds was investigated by 1H qNMR and chemometrics. Oligosaccharides, niacin, citric and lactic acids ranged according to phenotype. 13C CP and SPE/MAS ssNMR were applied to study mobile components in the cotyledons. Composition ranged between rigid (starch) to soft portion (fatty acids, protein). 1H T1ρ data suggests the presence of lipid-amylose complexes.
