Pharmaceutical composition for preventing and treating chronic obstructive lung disease containing, as active ingredient, Magnoliae flos extract, fraction, or active fraction thereof
A pharmaceutical composition includes any of an extract of Magnoliae flos, a fraction or an active fraction obtained by fractionation thereof with an organic solvent, and a compound separated therefrom as an active ingredient. The extract of Magnoliae flos, the fraction or the active fraction obtained by fractionation thereof with an organic solvent, or the compound separated therefrom inhibits the expression of MUC5AC induced by TNF-α and the promoter activity in human lung cancer mucosal cells (H292), reduces the number of inflammatory cells in the bronchoalveolar lavage fluid of the chronic obstructive pulmonary disease mouse model, inhibits the production of reactive oxygen species, and reduces the cytokines; and therefore are effective in preventing or treating chronic obstructive pulmonary disease.
