Sonchus oleraceus Residue Improves Nutritive and Health-Promoting Value of Common Bean (Phaseolus vulgaris L.): A Metabolic Study

Abstract

This study was conducted to evaluate the use of the phenolic-rich Sonchus oleraceus residue as an environmentally safe approach to induce the nutritive and health-promoting values of common bean ( Phaseolus vulgaris L. cv. Bronco). S. oleraceus shoot residue, at rates of 150 and 300 g m, has improved soil fertility via accumulation of soil macronutrients, organic matter, organic carbon, and total phenolics. The growth and yield of bean were significantly increased. Moreover, chemical composition of the treated seeds was significantly altered, whereas higher levels of total antioxidant capacity, proteins, carbohydrates, and most of the individual phenolic acids, flavonoids, vitamins, essential amino acids, and unsaturated fatty acids were recorded. Interestingly, a concentration dependent effect was also observed, for instance, a lower saturated-to-unsaturated fatty acid ratio was only observed in the case of the lower residue rate. These findings recommend the use of S. oleraceus in organic farming of bean to enhance the health benefits of the produced seeds.

Allelopathic interference of Sonchus oleraceus L. with wheat and the associated weeds: a field study

“…It was therefore necessary for wide-ranged researchers interested and specialized in this field to fill this gap. On the other hand, the amounts of residue application of such weed that were similar to those applied the current study stimulated growth and productivity of kidney bean crop (Hassan et al, 2018). In the view of these statements, I tested the hypotheses that (i) the strongly allelopathic S. oleraceus can display adverse effects on emergence and growth of the common weeds associated with wheat under field conditions and (ii) a potential stimulatory or, at least, no effect on the crop tested (i.e.…”

“…Furthermore, it is considered as an environmentally safe tool for weed control (Lemessa & Wakjira, 2015). Within this context, there is an existing trend to incorporate ecological practices to the agroecosystems so as to design alternative and sustainable cropping systems (Hassan et al, 2018) either for weed management or crop safety.…”

“…Therefore, this weed may give heavy biomass. Moreover, it may provide a cheapest, highly available and environmentally safe material to be used in the agroecology in terms of potential weed management due to its allelopathic capacity (Gomaa et al, 2014;Hassan et al, 2014b) and natural biofertilizer to enhance crop yield due to its fertilizing agency (Hassan et al, 2018).…”

Polyphenols: A concise overview on the chemistry, occurrence, and human health

“…Stilbenes are reported to be present in grapes, almond, bean, blueberries, bilberries, peanuts, grapevine, cranberries, mulberries, plum, and wine (Arraki et al, ; Błaszczyk, Sady, & Sielicka, ; Chang, Alasalvar, Bolling, & Shahidi, ; Hassan, Saleh, & AbdElgawad, ; Shrikanta, Kumar, & Govindaswamy, ). The recent review of El Khawand, Courtois, Valls, Richard, and Krisa () remarked how stilbenes present a high diversity in their phenolic structures (various chemical substituents and polymerization), which is a determining factor for their absorption and metabolism rates (El Khawand et al, ).…”

“…Stilbenes are reported to be present in grapes, almond, bean, blueberries, bilberries, peanuts, grapevine, cranberries, mulberries, plum, and wine (Arraki et al, 2017;Błaszczyk, Sady, & Sielicka, 2019;Chang, Alasalvar, Bolling, & Shahidi, 2017;Hassan, Saleh, & AbdElgawad, 2018;Shrikanta, Kumar, & Govindaswamy, 2015). RCTs does not suggest any benefit of its supplementation on cardiovascular risk factors (Sahebkar et al, 2015).…”
