“…Compounds 28 and 29 were tentatively identified as rutin and allivicin with precursor ions [M – H] − m / z 609.1457 and [M – H] − m / z 609.1519, respectively. There are many pharmacological properties of rutin, including antibacterial, antiprotozoal, antitumor, anti-inflammatory, antiallergenic, antiviral, cytoprotective, vasoactive, hypolipidaemic, antiplatelet, and antihypertensive. , …”

Fresh Wolffia globosa, the smallest flowering plant well-known for its favorable nutrient composition and rich content of bioactive compounds, was subjected to boiling, freeze−thawing, and mechanical crushing to reduce its excessive (95−96%) moisture level and consequent drying time. The resultant three wolffia matrixes were filtered through a plankton net to fractionate into the residue and the filtrate. The proximate composition, bioactive metabolites, antioxidant activity, and characterization of bioactive metabolites by LC-ESI-QTOF-MS/MS and Fourier transform infrared spectroscopy were made from oven-dried residues and filtrates. Among residues, crude protein (29.84%), crude lipid (5.77%), total carotenoids (TCC; 722.8 μg/g), and vitamin C (70.02 mg/100 g) were the highest (p < 0.05) for freeze−thawing against higher ash (7.99%), total phenolic content (TPC; 191.47 mg GAE g −1 dry weight), total flavonoid content (TFC; 91.54 mg QE g −1 dry weight), DPPH activity (47.46%), and ferric reducing antioxidant power (FRAP) activity (570.19 μmol FeSO 4 equiv/mg) for the crushed counterpart and Chl-b in residues from boiling. No significant variation was evident in the total tannin content (TTC). Among filtrates, higher total phenolic content (773.29 mg GAE g −1 dry weight), TFC (392.77 mg QE g −1 dry weight), TTC (22.51 mg TAE g −1 ), and antioxidant activity as DPPH activity (66.46%) and FRAP (891.62 μmol FeSO 4 equiv/mg) were evident for boiling, while that from crushing exhibited the highest TCC (1997.38 μg/g DM). LC-ESI-QTOF-MS/MS analysis identified 72 phenolic compounds with the maximum in residue (33) and filtrate (33) from freeze−thawing, followed by crushing (18 and 19) and boiling (14 and 13) in order, respectively. The results indicated that the predrying cell rupturing method significantly impacted quantitative, as well as qualitative compositions of residues and filtrates from fresh wolffia.

“…Therefore, it is of utmost importance to determine the appropriate doses of NPs-ZnO that stimulate crop yield and quality. On the other hand, grapevine (Vitis vinifera L.), is one of the most important perennial crops in the world (Tello et al, 2019) and is considered a functional food due to its high content of bioactive compounds, which are related to disease prevention (Huber et al, 2021;Krasteva et al, 2023;Kaushik et al, 2023), and it is also a crop very sensitive to Zn deficiencies (García-López et al, 2019). For the above-described NPs-ZnO can be an alternative to increasing the yield and quality of grapevine berries.…”

The low availability of micronutrients in the soil leads to a deficit of these micronutrients in crops, causing malnutrition in the population. Approximately 3,000 million people in the world have health problems caused by inadequate Zn intake. Agronomic biofortification is a way to produce crops rich in micronutrients and mitigate malnutrition problems. Nano biofortification with zinc oxide nanoparticles (NPs-ZnO) is a good strategy to mitigate and increase the nutritional content of the edible part of the plant. The aim was to determine the effect of foliar spraying with NPs-ZnO on yield and biosynthesis of enzymatic and non-enzymatic antioxidant compounds and their bioaccumulation. In this study, the effect of foliar fertilization with NPs-ZnO: 0, 25, 50, 75, and 100 mg L-1, on yield, the content of bioactive compounds and their bioaccumulation in grapevine berries was evaluated. The distribution of the treatments was under a completely randomized design, each treatment consisted of 10 plants, each representing one experimental unit. The treatments were applied by foliar sprays at fruit formation, in veraison and 15 days before harvest. Foliar spraying with NPs-ZnO positively modifies yield, the content of bioactive compounds, and their bioaccumulation. Doses of 50-75 mg L-1 of NPs-ZnO increased crop yield, and oenological parameters. In addition, all doses evaluated modified enzymatic and non-enzymatic antioxidants, and improving Zn concentration in grapevine berries. Foliar spraying of NPs-ZnO is an alternative to improve grape quality and yield, in addition to enriching its nutritional and antioxidant content.
