PMID: 19429316 Abstract Title: Inhibitory effects of Solidago chilensis Meyen hydroalcoholic extract on acute inflammation. Abstract: AIM OF THE STUDY: Alcoholic or hydroalcoholic preparations of the plant Solidago chilensis Meyen (Asteraceae) are employed in popular medicines to treat inflammation. The anti-inflammatory effects of the hydroalcoholic extract of aerial parts of the plant (93% ethanol) were investigated and the main components of the extract were identified.MATERIALS AND METHODS: Ear oedema was induced in male Wistar rats by topical application of the chloroform fraction of latex-extract from Euphorbia milii. Leukocyte mobilisation was quantified after air-pouch inflammation evoked by oyster glycogen. Leukocyte-endothelial interactions and mast cell degranulation were quantified by intravital microscopy. The extract itself was characterised via HPLC-DAD-MS and HPLC-MS/MS.RESULTS: Topical (12.5-50mg/kg) or intraperitoneal (25 or 50mg/kg) administrations of the extract reduced ear oedema formation (>25% reduction). Intraperitoneal applications of 25mg/kg of extract inhibited the migration of polymorphonuclear cells into the inflamed cavity (about 50%).
