Chemical composition and anti-inflammatory activity of the essential oils of Piper gaudichaudianum and Piper mikanianum.

Ethnopharmacological Relevance: Inflammation is the body's normal protective response to injury and is stimulated by pathogens, toxic compounds, damaged cells or radiation, promoting healing and restoring homeostasis to the injured tissue. Leaves of Piper gaudichaudianum Kunth, known as "pariparoba" are widely used in folk medicine for the relief of toothache, while the fresh roots are used as anti-inflammatory and to treat liver disorders. For P.

Antimicrobial Activity of Volatile Oils from Brazilian Stingless Bees Melipona quadrifasciata quadrifasciata and Tetragonisca angustula Propolis.

Few studies were performed on the volatile components' properties of propolis from native Brazilian stingless bees. This work sought to extract, chemically characterize, and evaluate of the antimicrobial properties of volatile oils from propolis of the stingless bees Melipona quadrifasciata quadrifasciata (MQ) and Tetragonisca angustula (TA). The volatile oils from the pulverized propolis samples were obtained in a Clevenger apparatus and characterized by gas chromatography coupled to mass spectrometry (GC/MS) and to flame ionization detector (GC-FID).

Two morphotypes versus two chemotypes of Psidium cattleyanum: Chemical and pharmacological comparison and a rational approach for marker selection.

Psidium cattleyanum has two morphotypes: one with yellow fruits and other with red fruits. The leaves are popularly used as anti-inflammatory. However, no distinction is made between the types.

Curcumin and n-acetylcysteine cocrystal produced with supercritical solvent: characterization, solubility, and preclinical evaluation of antinociceptive and anti-inflammatory activities.

Curcumin presents a promising anti-inflammatory potential, but its low water-solubility and bioavailability hinder its application. In this sense, cocrystallization represents a tool for improving physicochemical properties, solubility, permeability, and bioavailability of new drug candidates. Thus, the aim of this work was to produce curcumin cocrystals (with n-acetylcysteine as coformer, which possesses anti-inflammatory and antioxidant activities), by the anti-solvent gas technique using supercritical carbon dioxide, and to test its antinociceptive and anti-inflammatory potential.

Polyphenolic Composition and in Vitro Antihypertensive and Anti-Inflammatory Effects of Cuphea lindmaniana and Cuphea urbaniana.

The present study investigates the chemical composition, anti-inflammatory, and antihypertensive activities, in vitro, from extracts of Cuphea lindmaniana and Cuphea urbaniana leaves. The extraction was performed ultrasound-assisted, and UHPLC/MS analysis was in positive mode ionization. The anti-inflammatory activity of the extracts and miquelianin were assayed at concentrations 0.

Anti-Inflammatory Effects of Seed Extract Obtained from Supercritical CO.

is a plant species traditionally used in the treatment of diabetes, fever, hypercholesterolemia, obesity, and urinary tract diseases. The anti-inflammatory effects of leaves in mice were already known. Nevertheless, studies on the anti-inflammatory activity of its seeds are still lacking.

spp.: antichemotactic study for a potential anti-inflammatory drug.

genus (Lythraceae) popularly known in Brazil as "", it's described as antimicrobial, anti-inflammatory, diuretic and antihypertensive mainly. Investigating the chemotactic ability plays an important role in the identification of new anti-inflammatory agents. Thus, this research aims to assay the antichemotactic activity of hydroethanolic extracts of , , , and as well as the compounds miquelianin and myricitrin.
