Chemical profile, antioxidant and anti-inflammatory properties of Miconia albicans (Sw.) Triana (Melastomataceae) fruits extract.
ETHNOPHARMACOLOGICAL RELEVANCE: Miconia albicans (Sw.) Triana has been widely used in Brazilian popular medicine for the treatment of several diseases. Aerial parts are used as an infusion to treat arthrosis and arthritis, to relieve rheumatic and stomach pains, and intestinal disorders due to its anti-inflammatory, anti-mutagenic anti-nociceptive, digestive and hepatoprotective properties. AIM OF THE STUDY: This study aimed to characterize the of M. albicans (Sw.) Triana fruits extract (MAFRE) chemical profile and to evaluate its antioxidant, anti-inflammatory and antitumor activities, as wel

Conidiomata of a fungus resembling Chrysoporthe cubensis, a serious canker pathogen of Eucalyptus spp. (Myrtaceae, Myrtales) in tropical and subtropical parts of the world, was found on Eucalyptus grandis in Colombia. Fruiting structures of the fungus could be distinguished from those of C. cubensis by their distinctly orange conidiomatal necks. This fungus also was found on several plant species native to Colombia including Tibouchina urvilleana, T.

BACKGROUND: Given the rising occurrence of antibiotic resistance due to the existence and ongoing development of resistant bacteria and phenotypes, the identification of new treatments and sources of antimicrobial agents is of utmost urgency. An important strategy for tackling bacterial resistance involves the utilization of drug combinations, and natural products derived from plants hold significant potential as a rich source of bioactive compounds that can act as effective adjuvants. This study, therefore, aimed to assess the antibacterial potential and the chemical composition of Miconia al

The study aimed to assess the chemical composition of Miconia ibaguensis leaves extracts and fractions obtained from the ethanolic extract (EE), along with evaluating their antifungal, antibacterial, antidiabetic, and antioxidant activities. The ethyl acetate fraction (EAF) exhibited potent antifungal activity against Candida spp (1.95-3.90 μg mL
PubMed: 38748618Leishmanicidal and antimicrobial activity of primin and primin-containing extracts from Miconia willdenowii.
As a part of an ongoing bioprospective project, searching for potential medicinal plants from the Brazilian Atlantic Forest, Miconia willdenowii was selected for its potential leishmanicidal and antimicrobial activities. The crude ethanolic extract of M. willdenowii showed an inhibition of 99.7% of the promastigote forms of Leishmania amazonensis at the concentration of 80 μg/mL. Further investigation of its antimicrobial activity against pathogenic fungi and Gram positive and negative bacteria, revealed a significant antimicrobial activity. A bioguided study with its liquid-liquid partition f
PubMed: 31404617Seguridad y Precauciones
La seguridad del uso de Miconia theaezans no ha sido establecida mediante ensayos clínicos controlados en humanos, lo que representa una limitación crítica para su consumo terapéutico y requiere extrema precaución. En cuanto al embarazo y la lactancia, no existen estudios que garanticen la ausencia de efectos teratogénicos o la transferencia de metabolitos secundarios a través de la leche materna; por tanto, se desaconseja su uso debido al riesgo potencial de que los compuestos fenólicos interfieran con el desarrollo embrionario o la nutrición del lactante. Para niños menores de 12 años, la falta de datos sobre la toxicidad aguda y crónica en organismos en desarrollo impide su recomendación, siendo especialmente delicada la sensibilidad de su mucosa gastrointestinal a los taninos presentes en la planta. Respecto a las interacciones farmacológicas, existe un riesgo teórico significativo con la warfarina, ya que los flavonoides presentes en el género Miconia pueden alterar la cascada de coagulación o la actividad de la vitamina K, modificando el tiempo de protrombina. Con la metformina, los taninos podrían quelar el fármaco o alterar su absorción intestinal, afectando el control glucémico. Asimismo, en pacientes que toman antihipertensivos, la posible acción vasodilatadora de los polifenoles podría potenciar el efecto hipotensor, provocando desmayos o mareos por hipotensión excesiva.
