【Abstract】 Objective To study the antitussive and expectorant effects of Tonghao extraction. Methods Five groups were separated as negative control,Tonghao extraction( 0. 4,0. 2,0. 1ml) groups and positive control which used fritillary bulb cough syrup. Ammonia causing cough assay and phenol red excretion assay were employed to estimate the antitussive and expectorant effects of Tonghao extraction. Results Tonghao extraction could significantly prolong the latent period of cough,reduce the cough times and increase the amount of phenol red excreted from the mice’s trachea. Conclusion The results of our research suggested that Tonghao extraction has the effects of antitussive and expectorant,which could be used in food therapy.更多还原
