Honeybee pollen (HBP) is a mixture of floral collected by honeybees near the hive. It characterized composition rich in phenolic compounds, carotenoids and vitamins that act as free radicals scavengers, conferring antioxidant antibacterial capacity to matrix. These bioactive properties are related botanical origin honeybee pollen. samples were from different geographical locations central Chile, their total carotenoid content, polyphenols profile HPLC/MS/MS, DPPH radical scavenging capacity,...
Sticherus squamulosus, Hymenophyllum dentatum, Blechnum microphyllum, Polypodium Feuillei, chilense, Lophosoria quadripinnata, and Lissopimpla excelsa are native fern species found in southern Chile often used traditional medicine. However, their bioactive properties have not been confirmed. In this study, ethanolic extracts of ferns exhibited significant antibacterial capacity against human pathogens. H. dentatum S. squamulosus were selected for further analysis owing to antimicrobial...
Tristerix corymbosus flower is used in traditional medicine for its antioxidant and antibacterial properties, which are attributed to phenolic compounds. These compounds present different grades of associations with the plant matrix (free, esterified, insoluble). This study aimed determine fraction contributes most total flavonoid contents bioactive properties. The content was higher free fraction. In contrast, esterified exhibited highest greatest number characterised (chlorogenic,...
Plant growth-promoting rhizobacteria (PGPR) induce changes in the plant metabolism, improving growth under drought stress conditions by employing different mechanisms of interaction. In this study, two bacterial strains (Enterobacter sp. LHB11 and Bacillus PIXIE) were evaluated vitro regarding their PGPR traits, including ACC-Deaminase enzyme activity. Both produced indole acetic acid (40.65–75.81 µg−1mL−1), exopolysaccharides (39.23–40.20 µg eq CR mL−1), proline (61.5–106.1 mM), volatile...
The Mayten tree (Maytenus boaria Mol.), a native plant of Chile that grows under environmentally limiting conditions, was historically harvested to extract an edible oil, and may represent opportunity expand current vegetable oil production. Seeds were collected from trees in north-central Chile, seed extracted by solvent extraction. showed reddish coloration, with quality parameters similar those other oils. fatty acid composition revealed high levels monounsaturated polyunsaturated acids....
Myrtaceae fruits (Myrceugenia obtusa, Luma apiculata, and chequen) were used as food medicine by Chilean indigenous people. This study aimed to evaluate the bioactive properties of these berry-type fruits. The antioxidant capacity determined FRAP assay varied between 10.4 646.9 mmol Fe+2/g, while antibacterial activity against Staphylococcus aureus Salmonella typhi was 0 - 33 mm 7.33 mm, respectively. All extracts rich in polyphenols showed low cytotoxicity. Overall, M. obtusa presented...
