[Objective]To study anti-inflammatory effects of water extract of the stems and leaves of Platycodon grandiflorum. [Methods]Observed anti-inflammatory effects of extract of the stems and leaves of Platycodon grandiflorum using 4 kinds of animal models of acute inflammation which was consisted of rats footpad swelling induced by egg white,ear swelling caused by xylene in mice,celiac capillary permeation in mice induced by 1% glacial acetic acid and content of PGE2in inflammatory tissue of rats’ swelling foot induced by egg white. [Results]Extract of the stems and leaves of Platycodon grandiflorum had a certain degree inhibition effect on ear swelling caused by xylene in mice,rats’ footpad swelling and content of PGE2in inflammatory tissue of rats’ swelling foot induced by egg white and celiac capillary permeation in mice induced by acute inflammation. Compared with model group,parts of the stems and leaves of Platycodon grandiflorum that contained alkaloid were of significant differences( P < 0. 05 or P < 0. 01). [Conclusions] Parts of the stems and leaves of Platycodon grandiflorum that contained alkaloid had strong anti-inflammatory effects and other parts also had various degrees of anti-inflammatory effects.
