Application of amentoflavone in research and development of medicines for treating pneumonia

The invention relates to application of amentoflavone in research and development of medicines for treating pneumonia. Rabbit erythrocyte haemolysis tests, human pulmonary epithelial cell (A549) injury protection tests and a mouse streptococcus pneumonia model prove that the amentoflavone has a treatment effect on infection of streptococcus pneumonia. Compared with treatment with antibiotics, the amentoflavone for treatment has the characteristics of no drug resistance and high protection performance.
