代谢组分析华北驼绒藜开花结实期的营养价值OA

This study explored nutrient changes in Ceratoides arborescens at the molecular level by conducting metabolomic analyses on shoot tip tissues of three ecotypes during their flowering and fruiting stages.Key nutritional metabolites,including fatty acids,carbohydrates,and amino acids,are systematically evaluated.The results demonstrated three major trends:①Among fatty acid differential metabolites,prostaglandin 2,methylheptenone,and 2,4-dihydroxyheptadec-16-ynyl acetate showed consistent significant variations during the flowering and fruiting stage,with the highest accumulation observed in October.②For amino acid differential metabolites,L-Histidine and L-asparagine undergo continuous fluctuations,displaying significant accumulation in September(P<0.05).③ Carbohydrate differential metabolites,n6-isopentenyladenosine,D-fructose 6-phosphate,and myo-inositol,were significantly upregulated in all three ecotypes in September(P<0.05).These findings highlight substantial enrichment of critical nutritional metabolites from September to October,indicating elevated nutritional value in Ceratoides arborescens during its fruiting phase.
