KGaA, WeinheimBioactive phytoprostanes and phytofurans are synthesized in higher plants by non-enzymatic oxidation of ¿-linolenic acid (C18:3 n-3), triggered by high concentrations of reactive oxygen species. In the current scenario of changing dietary patterns, additional information is needed on the concentrations of oxylipins in legumes and on the effect of sustained deficit irrigation on their concentration. The main objective of the work is to elucidate the phytoprostane and phytofuran profile (including eight and three compounds, respectively) of three Pisum sativum cultivars (¿mangetout¿ (ssp. arvense), ¿BGE-033620,¿ and ¿Lincoln¿) and Phaseolus vulgaris (French bean cv. ¿Helda¿), to unravel the oxidative response of these crops to sustained irrigation deficit in terms of oxidative stress, as well as in their importance as healthy dietary sources of new bioactive compounds. Phytoprostanes and phytofurans vary between varieties and species, with 9-F1t-PhytoP and ent-16-(RS)-13-epi-ST-¿14-9-PhytoF being the most abundant. The level of phytoprostanes and phytofurans is also determined in sustained deficit irrigation (50% water needed), revealing modifications of their profile and concentration. In conclusion, bioactive phytoprostanes and phytofurans are present in legumes in high concentrations, being further modified by abiotic stress growing conditions, highlighting the importance of this plant food as a dietary source of these bioactive molecules. Practical Applications: This work is of high relevance from the lipidomic point of view, given that phytoprostanes and phytofurans have been promoted as new bioactive secondary metabolites due to their structural analogy with mammal oxylipins. These compounds can be further postulated as possible markers for the monitoring of the physiological status of legume plants under different agronomical conditions. The results obtained can contribute to the successful development of future research in the field of plant physiology and nutrition, significantly contributing to the advance of the current knowledge on the biological role of phytoprostanes and phytofurans in plants and complex biological systems. Species-dependent modification of phytoprostanes and phytofurans by deficit irrigation in French-bean, pea, and mangetout.
