Metabolite Fingerprinting of Kersting's Groundnut [ (Harms) Maréchal & Baudet] Seeds Using UPLC-qTOF-MS Reveals the Nutraceutical and Antioxidant Potentials of the Orphan Legume.

The identification and subsequent quantification of phenolic compounds in plants is the first step toward harnessing their associated nutritional and health benefits. Due to their diverse phenolic compound compositions, grain legumes are known for their high nutritional and health values. The aim of this study was to assess the inter-variations in chemical composition, phytochemical content, and antioxidant capacity of seed extracts from eight Kersting's groundnut [ (Harms) Marechal & Baudet] landraces.

Seed coat metabolite profiling of cowpea ( L. Walp.) accessions from Ghana using UPLC-PDA-QTOF-MS and chemometrics.

Cowpea ( L. Walp.) is an important grain legume in Africa exhibiting high morpho-genetic diversity.

Phytochemical profile of seeds from 21 Bambara groundnut landraces via UPLC-qTOF-MS.

Bambara groundnut is one of the under-utilized African legume crops, valued for its nutritional and health benefits, and for which ongoing studies will help to distinguish its many landraces and select the promising one for breeding programs. To describe the polar metabolome of the seed from 21 Bambara groundnut landraces, untargeted metabolomics approach using UPLC-qTOF-MS (Ultra performance liquid chromatography-Quadrupole time of flight mass spectrometry) was performed. Metabolites belonging to varied compound classes were detected and identified.

Nitrate inhibition of N fixation and its effect on micronutrient accumulation in shoots of soybean ( L. Merr.), Bambara groundnut ( L. Vedc) and Kersting's groundnut ().

Although nitrate is known to inhibit nodulation and N fixation in symbiotic legumes, little is known about its effect on the uptake and accumulation of trace elements such as Fe, Zn, Mn and Cu. The aim of this study was to evaluate the effect of 5 mM NO supply, either with or without rhizobial inoculation, on nodulation, nodule functioning and micronutrient levels in the shoots of soybean ( L.Merr.
