Chamaecrista pumila has empirically been used to treat inflammation-associated complications. However, the molecular mechanism and chemical components underlying the anti-inflammatory activity of this medicinal plant are poorly understood. Hence, the present study aimed to identify main bioactive compounds from the ethyl acetate fraction of C. pumila extract, which was demonstrated to possess the strongest anti-inflammatory effect in a previous study, and provide mechanistic insights into modulation of inflammatory responses by the compound of interest.

A Abatement: Reducing the degree or intensity of, or eliminating, pollution. Abatement Debris: Waste from remediation activities. Absorbed Dose: In exposure assessment, the amount of a substance that penetrates an exposed organism's absorption barriers (e.g.,, skin, lung tissue, gastrointestinal tract) through physical or biological processes. The term is synonymous with internal dose. Absorption Barrier: Any of the exchange sites of the body that permit uptake of various substances at different rates (e.g., skin, lung tissue, and gastrointestinal-tract wall).
