In dieser Studie wurden die antioxidativen, entzündungshemmenden und antiarthritischen Eigenschaften von hydroalkoholischen Extrakten und Fraktionen von Ixora coccinea L. untersucht. Die hydroalkoholischen Extrakte wurden durch Mazeration der Blüten von Ixora coccinea gewonnen, die Fraktionen durch Flüssig/Flüssig-Trennung. Die chemische Charakterisierung erfolgte durch Hochleistungsflüssigkeitschromatographie in Verbindung mit Massenspektrometrie (HPLC/MS). Es wurden Tests zur Bewertung der antioxidativen, entzündungshemmenden und antiarthritischen Aktivität durchgeführt. Die...

This is an integrative review with the guiding research question: "What are the main problems in the context of arboviruses and what alternative do essential oils represent?".The bibliographic research was carried out from January to March 2021, through an electronic search in the following databases: Google Scholar, Scientific Electronic Library Online (SCIELO) and Virtual Health Library (BVS). The publications were analyzed and interpreted. At the end of the analysis and description of the study, the discussion of the results found and the synthesis of the knowledge produced through this...

L'étude du profil chimique, de l'activité antioxydante et anti-inflammatoire des nanoparticules d'argent (AgNPs) synthétisées à partir de la nanoémulsion d'huile essentielle de Piper nigrum (NEO) a été réalisée de manière inédite. Les nanoémulsions ont été préparées par la méthode d'inversion de phase et la synthèse des AgNPs a été réalisée par la méthode de réduction Agno3 Ag en utilisant la NEO. L'activité antioxydante a été évaluée par la méthode de coloration des radicaux d'Abts et l'activité anti-inflammatoire par la dénaturation des protéines. Le...

Investigated in an unprecedented way the chemical profile, antioxidant and anti-inflammatory activity of silver nanoparticles (AgNPs) synthesized from Piper nigrum essential oil nanoemulsion (NEO). The nanoemulsions were prepared with the phase inversion method and the synthesis of AgNPs was performed with the Agno3 Ag reduction method using NEO. Antioxidant activity was evaluated by Abts radical staining method and anti-inflammatory activity by protein denaturation. The main component of the EO was limonene (42.41%). The maximum Spr band was centered at 420 nm, indicating the characteristic...
