Artemisia annua L. (AA) has shown for many centuries important therapeutic virtues associated with the presence of artemisinin (ART). The aim this study was to identify and quantify ART other secondary metabolites in ethanolic extracts AA evaluate biological activity an inflammatory stimulus. In work, after extraction aerial parts different concentrations ethanol, quantified by HPLC HPLC-MS. addition, anthocyanins, flavanols, flavanones, flavonols, lignans, low-molecular-weight phenolics, phenolic acids, stilbenes, terpenes were identified semi-quantitatively determined UHPLC-QTOF-MS untargeted metabolomics. Finally, viability human neuroblastoma cells (SH-SY5Y) evaluated lipopolysaccharide (LPS). results show that is more concentrated samples extracted 90% ethanol. Regarding metabolites, only anthocyanins are all showed a protective action towards pro-inflammatory stimulus LPS. particular, anti-inflammatory effect leaf extract ethanol also confirmed at molecular level since reduction TNF-α mRNA gene expression observed SH-SY5Y treated

Citrus fruits exhibit a high level of different phytoconstituents, which the changes in parts fruit during ripening have not been thoroughly studied yet. Thus, this study, we investigated how pomelo (Citrus grandis L.) are modified throughout development two consecutive growing seasons. In detail, main phytochemical compounds, such as total phenolic content, flavonoid antioxidant capacity, DPPH free radical scavenging activity, Ferric reducing power (FRAP), and naringin tannin were analyzed. A systematic metabolism these compounds was found fruit, but some tissues showed fluctuating trend, suggesting dependence on season. Focusing tissue distribution membrane contained highest content; flavedo displayed capacities FRAP activities, whereas maximum accumulation noticed albedo. Instead, activity contents juice. Regarding possible bias pattern for those has development. From GC-MS analysis, 111 identified, where 91 common both Overall, results could be useful food processing industry guidelines excellent quality foods introducing health-beneficial products components into our daily diets.

Plant secondary metabolites (SMs) play crucial roles in plant-environment interactions and contribute greatly to human health. Global climate changes are expected dramatically affect plant metabolism, yet a systematic understanding of such influences is still lacking. Here, we employed medicinal aromatic plants (MAAPs) as model taxa performed meta-analysis from 360 publications using 1828 paired observations assess the responses different SMs levels accompanying traits elevated carbon dioxide (eCO2 ), temperature (eT), nitrogen deposition (eN) decreased precipitation (dP). The overall results showed that phenolic terpenoid generally respond positively eCO2 but negatively eN, while total alkaloid concentration was increased remarkably by eN. By contrast, dP promotes all SMs, eT exclusively exerts positive influence on compounds. Further analysis highlighted dependence SM moderators functional types, change or exposure durations, mean annual precipitation. Moreover, could be attributed variations C/N ratio soluble sugar levels, trade-off supposition contributed other than . Taken together, our predicted distinctive diverse MAAPs allowed us define potential responsible for these variations. Further, linking C-N metabolism growth-defence balance provided biological understandings terms metabolic regulation.

This study comprehensively investigates the physiological and molecular regulatory mechanisms of Camellia oleifera seedlings under drought stress with a soil moisture content about 30%, where exogenous abscisic acid (ABA) was applied via foliar spraying at concentrations 50 µg/L, 100 200 µg/L. The results demonstrated that appropriate ABA treatment can regulate state through multiple pathways, including photosynthesis, oxidative response, osmotic balance, thereby aiding in restructuring their response strategy. effectively activated antioxidant system by reducing stomatal conductance moderately inhibiting photosynthetic rate, thus alleviating damage caused stress. Additionally, promoted synthesis regulators such as proline, maintaining cellular turgor stability enhancing plant’s adaptability. real-time quantitative PCR related genes indicated enhanced to signaling pathway improved disease resistance regulating expression genes, while also membrane lipid stability. A comprehensive evaluation using membership function approach suggested µg/L may be most-effective mitigating effects practical applications, followed ABA. application for 7 h induced significant changes various biochemical parameters, compared water spray. Notably, superoxide dismutase activity increased 17.94%, peroxidase 30.27%, glutathione 12.41%, proline levels 25.76%. soluble sugars proteins rose 14.79% 87.95%, respectively. there decrease 31.15% malondialdehyde levels.

Melatonin can be considered a physiological protective agent against environmental stress because of its natural antioxidant ability. The main goal this study was to investigate the possible melatonin-positive effects on growth enhancement and drought tolerance quinoa (Chenopodium Willd) cultivars. To accomplish objective, we compared (100 % field capacity as control 40 capacity), priming (melatonin (MP), hydro (HP), non-priming (NP), cultivars (Titicaca, Giza1). Thus, obtained results indicated higher oxidative damage, lipid peroxidation, reduced chlorophyll content, which decreased seed yield more in Giza1 than Titicaca comparison with control. MP remarkably enhanced endogenous melatonin superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), ascorbate (APX) activity (1.57, 2.50, 1.40, 1.90, 2 times, respectively) (1.68, 4.50, 4, 2.6 respectively), NP, under stress. effectively protected chlorophylls carotenoids, while decreasing malondialdehyde (MDA) content through enzyme activation, facilitation soluble protein, well sugar synthesis osmolyte accumulation. Therefore, improved photosynthesis NP. Overall, showed relatively tolerance. Furthermore, ameliorated adverse consequences facilitated recovery susceptible such photosynthetic pigments, systems, osmotic adjustment, secondary metabolite production. novelty current is elucidation role induction quinoa.

There is little study on melatonin’s ability to prevent salt damage in eggplants, despite the fact that it a strong antioxidant plants has been found help mitigate variety of adverse challenges. In this study, we used “Anhui Eggplant No.8” as test material and simulated stress by irrigating roots with 150 mmol·L NaCl solution. Subsequently, treated eggplants different concentrations exogenous melatonin (0, 50, 100, 150, 200, 250 μmol·L) assessed plant traits an array physiological biochemical indices following application observe impact stress.
