Metabolic profile of sweet potato leaves and roots
A preliminary characterization of metabolic profile of sweet potato roots and leaves is important to identify compounds associate with nutritional value. Drapal et al 2019 described a metabolic profile of 27 cultivars of sweet potato including landraces and improved varieties.
A total of 130 metabolites were identified in leaf and storage root tissues harvested from 9-month-old plants grown at greenhouse conditions, four repetitions each. A third of all identified compounds were classified as part of the phenylpropanoid metabolism, while the other metabolites within the following metabolic groups: amino acids, sugars, tri-carboxyl acid cycle, sterols, membrane precursors and isoprenoids (Isopentenyl pyrophosphate-IPP derived). Different quantification methods were used ultra-high-performance liquid chromatography (UPLC), liquid chromatography-mass spectrometry (LC-MS), gas chromatography-mass spectrometry (GC-MS), and near-infrared reflectance spectroscopy (NIRS).
A set of 23 accessions in this study are available for distribution at the International Potato Center Genebank. A selection of 47 metabolites and their concentration (µg/g of dry weigh – DW) in leaves and/or roots is presented in this dataset. Mainly amino acids (Alanine, Arginine, Asparagine, Aspartic acid, γ-Amino butyric acid, Glutamic acid, Glycine, Histidine, Isoleucine, Leucine, Phenylalanine, Proline, Tryptophan, and Tyrosine), cell wall or membrane precursors (α-linolenic acid, Erythronic acid/Threonic acid, Gluconic acid, Linoleic acid, Palmitic acid, and Stearic acid), isoprenoids (Abscisic acid, α-Tocopherol, β-Carotene, γ-Tocopherol, Lutein, and Phytoene), phenolics (Caffeic acid, Cinnamic acid, Kaempferol-3-O-rutinoside, Kaempferol-3-O-rutinoside_1, o-Coumaric acid, Quercetin-glucoside malic acid, and trans-Caffeic acid), sugars (Fructose, Glucose, Glucose/Mannose/Galactose/Sorbose, Inositol, Mannose, and Sucrose), and tri- carboxyl acid cycle compounds (Citric acid, Fumaric acid, Isocitric acid, Maleic acid, and Malic acid).

Perfil de metabolitos de hojas y raíces de camote
La caracterización preliminar de la composición metabólica de las hojas y raices de camote es importante para identificar compuestos asociados con el valor nutricional. Drapal et al 2019 describieron un perfil metabólico de 27 cultivares de batata, incluidas variedades locales y variedades mejoradas.
Se identificó un total de 130 metabolitos en tejidos de hojas y raíces de almacenamiento cosechados de plantas de 9 meses de edad cultivadas en condiciones de invernadero, cuatro repeticiones cada una. Un tercio de todos los compuestos identificados se clasificaron como parte del metabolismo del fenilpropanoides, mientras que los otros metabolitos dentro de las siguientes rutas metabólicas: aminoácidos, azúcares, ciclo del ácido tricarboxílico, esteroles, precursores de membrana e isoprenoides (derivados de isopentenil pirofosfato-IPP). Se utilizaron diferentes métodos de cuantificación: cromatografía líquida de ultra alto rendimiento (UPLC), cromatografía líquida y espectrometría de masas (LC-MS), cromatografía de gases y espectrometría de masas (GC-MS) y espectroscopía de reflectancia infrarroja cercana (NIRS).
