“…Many studies reported that the inclusion of more fruits in the diet is good for our health because it may reduce the chance of many chronic diseases, such as cardiovascular disease, cancer, obesity and diabetes (Figure 3) [62,63]. These beneficial effects are attributed to the fact that fruits contain several phytochemical components, and phenolic compounds account for a large proportion [64][65][66][67][68][69]. The second apart of this review describes the bioactive components contained in unripe fruits, which occur at higher concentrations than mature fruits.…”

Fruit thinning is a cultivation technique that is widely applied in horticulture in order to obtain high-quality horticultural crops. This practice results in the discarding of a large number of thinned unripe fruits in orchards each year, which produces a great waste of agricultural resources and causes soil pollution that may be an important reservoir for pest and plant diseases. Current studies showed that bioactive compounds such as polyphenols, organic acids, monosaccharides and starches are present in unripe fruits. Therefore, we reviewed the bioactive components obtained from thinned unripe fruits, their revalorization for the food industry, their beneficial effects for human health and the methods for obtaining these components. We also performed a calculation of the costs and benefits of obtaining these bioactive compounds, and we proposed future research directions. This review provides a reference for the effective utilization and industrial development of thinned unripe fruits obtained from horticultural crops. Furthermore, revalorizing the waste from this cultural practice may increase the economic benefits and relieve the environmental stress.

“…Fe content in the neglected Brazilian vegetables ranged between 176.77 and 586.12 mg/kg. 53 Moura et al 54 showed 76.52, 88.69, and 126.75 mg/kg of Fe content in the leaves of white and purple I. batatas and T. triangulare, respectively. Their results showed a higher quantity of Fe in the I. batatas, whereas it was comparable in T. triangulare.…”

“…56 When compared with a few earlier studies, the results of the proximate composition of this study show some variation, which can be related to the changes in temperature, rain, sunlight exposure, soil characteristics, and growth status. 53 Overall results of the proximate analysis show that TLVs can be used as staple diets by people to ensure nutritional supply in an economical and environment-friendly manner. As the TLVs vary regionally, locally available plants need to be identified for their nutritive potential and can be included in the diets of the local people.…”

Traditional leafy vegetables (TLVs) are rich in beneficial bioactive compounds and mineral elements. The rural areas of Kerala, India, have a diversity of unconventional TLVs, and only limited research is available on their nutritional and biochemical composition. Therefore, this study was designed to evaluate the mineral elements, metabolites, antioxidants, antioxidant activity, and proximate composition of 14 TLVs. The results show that among the selected TLVs, Talinum triangulare exhibited the highest Zn (1214 mg/kg DW) content, whereas the highest amount of Ca (13,532 mg/kg DW) was found in Centella asiatica. GC−MS analysis of these 14 plants unveiled a total of 193 metabolites. The metabolic pathways with high impact were associated with alanine, aspartate, glutamate, galactose, and glyoxylate−dicarboxylate metabolism and aminoacyl tRNA synthesis. Several metabolites showed differential expression across the samples. Celosia argentia, Ipomoea batatas (sweetheart cultivar), and Ipomoea aquatica showed the highest expression of metabolites such as caffeic acid and xylitol. I. batatas cv. sidekick black (0.49 mg/mL) and Cnidoscolus aconitifolius (0.135 mg/mL) demonstrated the highest antioxidant activities. The 14 plants had varying levels of fiber (2.01−7.31%), fat (2.68−9.36%), protein (4.55−22.32%), and carbohydrate (34.62−69.3%). Overall, these TLVs have high nutritional potential and health-protecting properties, which can boost the well-being of consumers.

“…Metabolomics focuses on the complete analysis of all metabolites present in a biological system of interest [ 19 ]. To attain this goal, metabolomics is based on rapidly evolving technologies often integrated in systems biology to study the interactions between the different functional levels of biological organisms [ 20 , 21 , 22 ]. In recent years, liquid chromatography (LC) and ultra-high performance liquid chromatography (UHPLC) coupled with high resolution mass spectrometry (HRMS) techniques, have become state-of-the-art methods for multi-omics studies due to their ability to identify a large range of low abundant molecules including secondary plant metabolites [ 23 ].…”

Background: An important goal of modern medicine is the development of products deriving from natural sources to improve environmental sustainability. In this study, humic substances (HS) and compost teas (CTs) extracted from artichoke (ART) and coffee grounds (COF) as recycled biomasses were employed on Ocimum basilicum plants to optimize the yield of specific metabolites with nutraceutical and antibacterial features by applying sustainable strategies. Methods: The molecular characteristics of compost derivates were elucidated by Nuclear Magnetic Resonance spectroscopy to investigate the structure–activity relationship between organic extracts and their bioactive potential. Additionally, combined untargeted and targeted metabolomics workflows were applied to plants treated with different concentrations of compost extracts. Results: The substances HS-ART and CT-COF improved both antioxidant activity (TEAC values between 39 and 55 μmol g−1) and the antimicrobial efficacy (MIC value between 3.7 and 1.3 μg mL−1) of basil metabolites. The metabolomic approach identified about 149 metabolites related to the applied treatments. Targeted metabolite quantification further highlighted the eliciting effect of HS-ART and CT-COF on the synthesis of aromatic amino acids and phenolic compounds for nutraceutical application. Conclusions: The combination of molecular characterization, biological assays, and an advanced metabolomic approach, provided innovative insight into the valorization of recycled biomass to increase the availability of natural compounds employed in the medical field.
