The aim of this study was to evaluate the activities of anti-inflammatory and analgesic of the total flavonoids extraction from Oxytropis falcate Bunge (FR)) after transdermal administration. The pharmacokinetics and absolute bioavailability of FE) in rat, furthermore, was studied. Firstly, the anti-inflammatory and analgesic effects of the FE were studied by xylene-induced ear edema, adjuvant-induced joint inflammation law in rats, acetic acid-induced writhing and hot-plate tests in mice. Secondly, we developed a sensitive and specific HPLC method to analyze 2', 4'-dihydroxychalcone (TFC, the mainly ingredient of FEO) in rat plasma to study the pharmacokinetic of TEC. The results showed FE has anti-inflammatory and analgesic property in a dose-dependent manner, and that the high dose group (90.6 mg/kg) of FEO appeared more significantly effective than the positive drug. From the pharmacokinetic studies of TFC in rats, we got the main pharmacokinetic parameters of TFC, providing a basis for the future studies in clinic. (c) 2010 Elsevier B.V. All rights reserved.
