Anti-Inflammatory and Antioxidant Properties of the Extract, Tiliroside, and Patuletin 3-O-β-D-Glucopyranoside from Pfaffia townsendii (Amaranthaceae).

ABSTRACT: Brazilian ginseng, including Pfaffia townsendii, is used in popular medicine as a natural anti-inflammatory, tonic, analgesic, and antidiabetic agent. In this study, we investigated the chemical composition and evaluated the antioxidant and anti-inflammatory activities of the P. townsendii ethanolic extract as well as the major isolated glycoside flavonoids tiliroside and patuletin 3-O-β-D-glucopyranoside. Chromatographic techniques and spectroscopic analysis were used for the isolation and identification of the major compounds. The antioxidant potential was determined through DPPH and ORAC-FL assays. The total phenolic content was measured using Folin-Ciocalteu reagent. The anti-inflammatory activity was determined based on a model of paw edema and carrageenan- (Cg-)
