Extreme environments significantly impact the metabolic profiles of plants, leading to variations in chemical composition and bioactivity. This study investigates effects altitude, plant part age, light exposure on antimicrobial properties Moringa peregrina. Based our results, mineral contents were location dependent; while dry matter, ash, total digestible nutrients (TDN), fibre, protein, tannins, greater samples from mountain. Vitamin E was more concentrated wadi. A, selenium, phenols, heavy metals undetectable both environments. Antimicrobial assays revealed stronger activity mountain than other locations. Age-dependent analyses showed that nitrogen, electrolyte leakage higher young parts, whereas chlorophyll a b levels elevated mature leaves younger branches, particularly lower elevations. Interestingly, regions had concentrations compared leaves, contrasting with trends at Photosynthetic photon flux density (PPFD) measurements also highest region. These findings suggest M. peregrina employs diverse adaptations for survival challenging environments, potentially offering socioeconomic value indigenous communities through its bioactive properties.

Influence of altitudes and development stages on the chemical composition and antioxidant capacity of Andean blackberries (Rubus glaucus Benth)

Frontiers in Nutrition, Journal Year: 2024, Volume and Issue: 11

Published: Nov. 6, 2024

Background The Andean blackberry ( Rubus glaucus Benth), locally known as “Mora de Castilla,” is a high-altitude fruit rich in phytochemicals, mainly anthocyanins, with potent antioxidant properties. Although its chemical composition has been studied, the influence of altitude on phytochemical profile and capacity still unclear. This research aimed to investigate effects development stages activity this fruit. Methods fruits were collected at different altitudes central region Ecuador. An hydroalcoholic extraction was used quantify compounds determine total activity, while solid phase (SPE) performed separate anthocyanins from other compounds. Ultra-high-performance liquid chromatography coupled triple quadrupole mass spectrometer (HPLC-DAD/ESI-MSn) identify anthocyanin non-anthocyanin phenols, capacity, polyphenols, flavonoid content, content quantified spectrophotometrically. Results Flavonols constitute majority flavonoids identified extracts, both terms peak areas number compounds, followed by ellagic gallic acid derivatives, well phenolic acids, hydroxycinnamic acids. Quercetin predominant flavonol unripe berries, where not significantly present. On contrary, ripe cyanidin glycosides stood out main We observed that early ripening, polyphenol predominates berries responsible for their capacity. However, ripens, increases, becoming most prominent bioactive fully berries. Conclusion results suggest higher environmental conditions may improve composition, concentration blackberries. Overall, our findings highlight high functional value fruit, supporting health-protective when consumed regularly, either fresh or nutraceutical form.

Chemical and nutritional characterization of loengo (Anisophyllea boehmii) fruits as a source of important bioactive with impact on health

Frontiers in Food Science and Technology, Journal Year: 2024, Volume and Issue: 4

Published: Dec. 19, 2024

Introduction Fruits are vital for promoting human health, as well providing nutrients and other compounds linked to protection against many different diseases. Loengo (Anisophyllea boehmii Engl.) produces an edible stone fruit, plum-shaped (drupe), dark blue maroon or carmine in the ripening stage, which is generally, consumed fresh production areas. Characterization of this fruit will contribute estimate its nutritional pharmaceutical potential impact. The present work aimed at physic-chemical, antioxidant activity characterization loengo fruit. Methods Soluble solid contents (SSC) pulp were assessed juice, room temperature. Total protein was determined using Dumas method. In what concerns mineral composition by ICP-OES. Organic acids identification quantification accomplished a high-performance liquid chromatography (HPLC) system. total polyphenol (TPC) 96-well microplate assays. Antioxidant 2,2-diphenyl-1-picrylhydrazyl (DPPH) ferric reducing power (FRAP) assay. Results discussion Composition, terms matter follows: soluble sugar content (refractometer) 19.5% ± 0.02%, titratable acidity 1.2% 0.1% expressed citric acid; 7.4% 8.0% 0.1%, 16.9% 0.2%, peel, seed, respectively. composition, results obtained show that it good source minerals, mainly potassium phosphorus, but also calcium, sulfur, magnesium, with richer potassium, seed peel calcium. As expected, showed highest content, whereas had lowest. main sugars found glucose fructose. acid organic found, together malic, oxalic, ascorbic acids. Most seed. provide important basic information recommend consumption sweet taste, chemical and, most all, richness phenolic formulate nutraceutical foods.
