Objective: To study the antipyretic and anti-inflammatory constituents from the active fraction of Reduning (RDN) Injection. Methods: In this study, the active fraction of RDN Injection was screened by the LPS-induced mouse endotoxin shock model. The chemical constituents were isolated by chromatography on HP-20 macroporous resin, silica gel, MCI, ODS, reverse MPLC, and HPLC repeatedly, and their structures were identified by spectral data and physicochemical property. Taking PGE2 as the evaluating indicator, the model of LPS-induced RAW264.7 cells was used to evaluare the in vitro anti-inflammatory activity of these compounds.
