“…Overall results show that the highest content of total phenolics was observed at treatment NS2 × C II. All nutrient elements present in NSs significantly influence the phenolic composition in plants by impacting the biosynthesis, accumulation, and distribution of phenolic compounds ( Heimler et al., 2017 ; Bustamante et al., 2020 ; Ebrahimian et al., 2021 ; Vilkickyte and Raudone, 2021 ) and nutrient levels and forms in solution can impact the quality and quantity of phenolics as well ( Vilkickyte and Raudone, 2021 ; Marlin et al., 2022 ). However, nitrogen is a major essential nutrient for plant growth and development, which also significantly influences the phenolic composition in plants.…”

IntroductionMore than ever, traditional agricultural practices need a shift towards more resilient, sustainable, modern and adaptable practices that benefit the health of the planet and people. Today's consumers are constantly on the lookout for novel, highly nutritious foods that have a positive impact on their overall health and well-being. Nettle (Urtica dioica L.) is gaining recognition not only as a popular medicinal plant, but also as a desirable green leafy vegetable rich in phytonutrients. As it is difficult and even expensive to control the quality standards of wild-collected plants, the implementation of sustainable cultivation methods, especially hydroponics, with effective greenhouse management could be a possible solution to obtain a standardized product with high nutritional value. Therefore, the aim of this study was to investigate the effects of four nutrient solutions differing in the content of macro- and micronutrients (especially nitrogen, potassium, calcium, magnesium and iron) and two consecutive cuts on the number of leaves, yield, nitrate and mineral content and the content of specialized metabolites of stinging nettle from a floating hydroponic system.MethodsNettle plants were cultivated in a hydroponic system using the floating hydroponics technique. The two-factorial experiment was performed with nutrient solution and consecutive cuts as factors.ResultsThe highest yield (2.49 kg/m2) was achieved after the 1st cut with plants cultivated in the nutrient solution with higher nutrient concentration. All tested nutrient solutions resulted in high levels of minerals and bioactive compounds in the plant material (ascorbic acid content of 102.30 mg/100 g fw and total phenolics content of 465.92 mg GAE/100 g fw), confirming floating hydroponics as a sustainable approach for cultivating nettle with enhanced nutritional value and antioxidant potential.ConclusionIt is important to highlight that the nutrient solution with the lowest nutrient composition yielded the highest concentrations of calcium (5.54%) and iron (180.67 mg/kg dw). Furthermore, it exhibited elevated levels of specific phenolic compounds, including caffeoylmaleic acid, ellagic acid, ferulic acid, naringin, and rutin trihydrate. Notably, this solution demonstrated the lowest nitrate content (4225.33 mg/kg fw) in the plant material. Therefore, it can be recommended as a preferable formulation for hydroponic nettle cultivation.

“…The content of secondary metabolites in different plant organs varies due to modifications of gene expression or of their encoded protein activity involved in secondary metabolism under the effects of different developmental stages and stresses [45]. The synthesis of phenolic compounds is a combinatorial biosynthesis, including the pathways of shikimate and acetate [46]. Further, in bilberry, genotype can significantly affect the amount and qualitative composition of different phenolic compounds in fruits [47].…”

Variation of Polyphenol Content and Antioxidant Activity in Some Bilberry (Vaccinium myrtillus L.) Populations from Romania

et al. 2021

Fruits of bilberry (Vaccinium myrtillus L.) are valued mainly for their nutraceutical properties, and are among the fruits with the highest antioxidant activity due to their high content of phenolic compounds. The aim of this research was to assess the total polyphenol content and antioxidant activity of fruits in six wild bilberry populations from two regions of Romania over three years. The total polyphenol content was determined according to the Folin–Ciocalteu modified method, while the antioxidant activity was evaluated using the DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging assay. The Padis and Raul Lung populations registered the highest values of polyphenol content and antioxidant activity, as such the fruits of these bilberry populations could be considered potential sources of antioxidants for direct consumption or for use as ingredients for food products or food supplements. Significant variation of total polyphenol content and antioxidant activity was observed both between populations from the same region and from different regions. The low level of broad sense heritability for total polyphenol content and antioxidant activity associated with the high effects of year, and population–year interaction indicates that the accumulation of polyphenols in bilberry fruits is influenced by changes in environmental conditions.

“…In view of this, an effective analytical strategy must be in place for a comprehensive evaluation of the functional constituents of lingonberry in different geographical regions. 14 However, current studies mainly focus on individual parts of lingonberries such as fruits, leaves or are reported for a separate group of components, 3,11 polyphenols, avonoids and triterpenes. 8,12 In addition, metabolites in plants are inuenced by a number of factors such as genotype, environmental conditions and geographical location.…”
