Geographical variation in the chemical composition, anti-inflammatory activity of the essential oil, micromorphology and histochemistry of Schinus terebinthifolia Raddi.

Ethnopharmacological Relevance: Schinus terebinthifolia Raddi (Anacardiaceae) is rich in essential oil, distinguished by a predominance of monoterpenes and sesquiterpenes, it being widely used in traditional medicine for the treatment of inflammations.

Aim Of Study: This study's objective was to investigate the chemical composition of the essential oil of S. terebinthifolia (EOST) collected in six states of Brazil, evaluate its anti-inflammatory effects in mice, and analyze the histochemistry and micromorphology of leaves and stems.

Exploration of essential oil from Psychotria poeppigiana as an anti-hyperalgesic and anti-acetylcholinesterase agent: Chemical composition, biological activity and molecular docking.

Ethnopharmacological Relevance: Leaves from Psychotria poeppigiana Müll. Arg. (accepted as Palicourea tomentosa (Aubl.

Chemical analysis and antioxidant, anti-inflammatory and toxicological evaluations of the hydromethanolic extract of Psidium guineense Swartz leaves.

Ethnopharmacological Relevance: Psidium guineense, popularly known as "araçá-do-campo", is used in popular medicine for the treatment of inflammatory diseases. Our research group studied an essential oil obtained from its leaves and reported anti-inflammatory and analgesic properties. However, to date, the anti-inflammatory actions of the leaf extract have not been evaluated although the traditional folk use of this plant has these indications.
