Abstract
Present study investigated triterpene profile, antihyperalgesic and antiedematous activities of Hieracium scheppigianum flowering aerial parts dichloromethane extract (SCH), and antihyperalgesic and antiedematous activities of previously chemically characterised polyphenol-rich H. glabratum and H. calophyllum flowering aerial parts methanol extracts (GLA and CAL, respectively). α- and β-Amyrin and their acetates, and lupeol acetate were identified and quantified in SCH by GC-FID and GC-MS. In carrageenan-induced localised inflammation model in rats, SCH and GLA (50–200 mg/kg, p.o.) produced significant and dose-dependent antihyperalgesic effect of 26.9%–56.2% (ED50=163.0 ± 26.5 mg/kg) and 25.3%–51.6% (ED50=211.6 ± 70.6 mg/kg), respectively, and CAL (200 mg/kg, p.o.) exhibited effect of 38.1%. Extracts did not significantly reduce paw edema. SCH and GLA, which demonstrated higher (over 50%) antihyperalgesic efficacy, were tested in a rotarod test (200 mg/kg, p.o.) and no alteration of m...otor coordination was observed. Also, acute administration of SCH and GLA in mice (2000 mg/kg, p.o.) caused neither mortality nor toxicity.
