“…When comparing with literature reports, our results show a larger number of compounds than those reported for whole plum fruits from Egypt, USA, Serbia and Romania [16,[28][29][30] in flavan-3-ols and HCA, as well as similar results in flavonoids to those found for Egyptian cultivars [29]. Within studies focused on plum skins, our results show a greater number of compounds than cultivars from the USA and Germany [7,31].…”

There is an increased interest in plum research because of their metabolites’ potential bioactivities. In this study, the phenolic profiles of Prunus domestica commercial cultivars (Methley, Pisardii and Satsuma) in Costa Rica were determined by Ultra Performance Liquid Chromatography coupled with High Resolution Mass Spectrometry using a quadrupole-time-of-flight analyzer (UPLC-ESI-QTOF MS) on enriched phenolic extracts obtained through Pressurized Liquid Extraction (PLE) under acidic and neutral extraction conditions. In total, 41 different phenolic compounds were identified in the skin and flesh extracts, comprising 11 flavan-3-ols, 14 flavonoids and 16 hydroxycinnamic acids and derivatives. Neutral extractions for the skins and flesh from all of the cultivars yielded a larger number of compounds, and were particularly rich in the number of procyanidin trimers and tetramers when compared to the acid extractions. The total phenolic content (TPC) and antioxidant potential using the DPPH and ORAC methods exhibited better results for neutral extracts with Satsuma skins and Methley flesh, which showed the best values (685.0 and 801.6 mg GAE/g extract; IC50 = 4.85 and 4.39 µg/mL; and 12.55 and 12.22 mmol TE/g extract, respectively). A Two-Way ANOVA for cytotoxicity towards AGS gastric adenocarcinoma and SW620 colon adenocarcinoma indicated a significant difference (p < 0.05) for PLE conditions, with better results for neutral extractions, with Satsuma skin delivering the best results (IC50 = 60.7 and 46.7 µg/mL respectively) along with Methley flesh (IC50 = 76.3 and 60.9 µg/mL, respectively). In addition, a significant positive correlation was found between TPC and ORAC (r = 0.929, p < 0.05), as well as a significant negative correlation (p < 0.05) between TPC and cytotoxicity towards AGS and SW620 cell lines (r = −0.776, and −0.751, respectively). A particularly high, significant, negative correlation (p < 0.05) was found between the number of procyanidins and cytotoxicity against the AGS (r = −0.868) and SW620 (r = −0.855) cell lines. Finally, the PCA clearly corroborated that neutral extracts are a more homogenous group exhibiting higher antioxidant and cytotoxic results regardless of the part or cultivar; therefore, our findings suggest that PLE extracts under neutral conditions would be of interest for further studies on their potential health benefits.

“…Our study revealed that 'Stanley' was the richest in TPC, whereas higher TAC was found in 'Čačanska Lepotica'. The pronounced influence ofgenotype was confirmed by Tomić et al (2019) in their study on the phytochemical assessment of 18 plum cultivars, with 'Stanley' showing the highest content of total phenols, thus being categorized into a group of cultivars with a high content of total phenols.…”

“…Due to their health benefits, the demand for fruits with high levels of phytochemicals, in particular phenolic compounds, has received increasing attention from breeders, pharmaceutical companies and consumers. Plums contain a wide range of phenolics (Tomić et al 2019;Sahamishirazi et al 2017;Jaiswal et al 2013;Miletić et al 2012;Cevallos-Casals 2006;Kim et al 2003;Stacewicz-Sapuntzakis 2001) which have been implicated in improving human health. The greatest benefit for human health is attributed to their antioxidant, anti-carcinogenic, antimutagenic, antimicrobial, anti-inflammatory and neuroprotective characteristics (Nile and Park 2014).…”

“…The greatest benefit for human health is attributed to their antioxidant, anti-carcinogenic, antimutagenic, antimicrobial, anti-inflammatory and neuroprotective characteristics (Nile and Park 2014). However, the quantity and quality of bioactive compounds in fruits are strongly related to genotype (Tomić et al 2019;Vizzotto et al 2007;Scalzo et al 2005), pre-and postharvest factors (Melgarejo et al 2012;Díaz-Mula 2009) and also to the applied growing technologies (Peck et al 2006;Veberic et al 2005;Carbonaro et al 2002). All these studies confirmed that fruits produced without the use of synthetic products (fertilizers and plant protection products) have a higher amount of micronutrients and health-related secondary metabolites, such as phenolic compounds.…”

Intensive agricultural development based on the long-term and excessive use of chemical nitrogen fertilizers significantly contributes to a series of undesirable effects and results in environmental pollution. In line with the above, there is a pressing need for major changes in agricultural production management. Bearing in mind that fertilization strategy, among other practices, plays an important role in improving the growing technology of different fruit crops, we considered that the above mentioned problems could be overcome by introducing an environmentally safe and innovative practice inplum growing technology as well. Accordingly, a comparative study was conducted to evaluate the effects of biofertilizer (a combination of nitrogen-fixing and phosphorus-mineralizing bacteria including Azotobacter chroococcum, Bacillus megatherium and Bacillus subtilis) and chemical fertilizer (a water-soluble chemical fertilizer supplemented with the microelements B, Cu, Fe, Mn and Zn)on ʻČačanska Lepoticaʼ and 'Stanley' plum cultivars. Morphometric characteristics (fruit weight, length and width), internal quality traits (soluble solids content and firmness) and chemical properties (total phenolic content and total antioxidant activity) of the fruit of the tested plum cultivars were assessed. The obtained results indicate that the substitution of chemical fertilization with biofertilization in 'Čačanska Lepotica' and 'Stanley' is a justified practice. Furthermore, this approach seems to havepotential as an appropriate technique in commercial plum production, which may improve yield-attributing characteristics and the phytochemical content of plum fruits.

“…The elution solvents were (A) 3% acetonitrile with 0.1% formic acid in double-distilled water and (B) 3% double-distilled water with 0.1% formic acid in acetonitrile. A linear gradient was adapted from Tomic et al [20]. In brief, 0-15 min, 5% solvent B; 15-20 min, 20% B; 20-30 min, 30% B; 30-35 min, 90% B; and 35-45 min, 100% B before returning to the initial conditions to the end of the run time.…”

Nitrogen is an integral element of foliar sprays during apple fruit formation. However, in red cultivars, the application may have adverse effects on color in the second stage of fruit development. The effect of a low-dose foliar application of urea was monitored on ‘Topaz’ apple pomometric (fruit mass, firmness, total solids, starch content, skin color) and biochemical traits (primary metabolites, phenolic compounds, and assimilatory pigments). Three applications (17 July, 27 July, and 18 August) of two different urea doses (N1 = 1.4 kg N ha−1; N4 = 4 kg N ha−1) and control (N0, only sprayed with water) were used. Low doses of urea did not affect flesh firmness, total soluble, solid, and starch content, but individual fruit mass was significantly higher in N1 treatment compared to the other two treatments. Significantly lower a* parameters and a lower content of anthocyanins were measured on apples subject to N4 treatment. Many secondary metabolites (phenolic acids, flavan-3-ols, flavonols, and chalcones) were also negatively affected by low-dose urea application. Conversely, urea treatments significantly increased total assimilatory pigments in apple skin. Even minor levels of nitrogen, applied directly on the leaf at later stages of red apple fruit development, negatively altered color traits and the composition of metabolites.
