High temperature treatment increases the content of several chromones, however using one or more individual constituents would be difficult to determine the medical quality of RS. In this paper, we used pharmacokinetic and pharmacologic approaches to evaluate the quality of RS. The active constituents were analysed using pharmacokinetic parameters of the chromone derivatives, and the antipyretic, analgesic, and anti-inflammatory effects were evaluated by pyretic animal model, hot plate test, and ear edema model, respectively. Only cimifugin was found in plasma after RS and heat-stress-RS were administered to rats, with a 50.6% increase in AUC0–24 h of cimifugin in the latter. Likewise, more potent anti-pyretic, analgesic, and anti-inflammatory activities were also found in the latter. Exposure of S. divaricata fresh roots to high temperatures enhanced the antipyretic, analgesic, and anti-inflammatory effects of RS by promoting the absorption of cimifugin.展开更多
