OBJECTIVE： To investigate antitussive， antiasthmatic， phlegm-resolving and anti-inflammatory effects of Fritillaria cirrhosa and Fritillaria unibracteata. METHODS： Mice and guinea pig were randomly divided into blank control group （distilled water）， ethanol extract groups， water extraction groups and powder groups of F. cirrhosa and F. unibracteata （1.13 g/kg for mice， 0.42 g/kg for guinea pig， calculated by crude drug）， positive control group， with 10 mice （guinea pig） in each group. Each group was given relevant medicine intragastrically once a day for consecutive 5 d. Relative indicators were detected 30 min after last medication. The ammonia water induced cough method was used to investigate antitussive effect （dextromethorphan hydrobromide as positive drug， 0.013 g/kg） by determining coughing latent period and coughing times within 3 min. After inducing asthma with 2％ histamine phosphate for 15 s， antiasthmatic effect （aminophylline as positive drug， 0.033 g/kg） was investigated by determining coughing latent period and the number of guinea pig with convulsive fall. The phenol red injection method was used to investigate phlegm-resolving effect （ambroxol as positive drug， 21.304 g/kg） by determining the content of phenol red in the trachea of mice in phenol red expectoration test. The anti-inflammatory effect （dexamethasone acetate as positive drug， 9.225×10－4   g/kg） was investigated by determining ear swelling degree and inhibition rate of ear swelling mice in xylene-induced inflammation test. RESULTS： Compared with blank control group， coughing latent period and cough induction latent period prolonged significantly in ethanol extract of F. cirrhosa and F. unibracteata groups， F. cirrhosa and F. unibracteata powder groups， positive control group， and coughing time decreased significantly within 3 min. The number of mice with convulsive fall decreased significantly in F. cirrhosa powder group， F. unibracteata ethanol group， F. unibracteata powder group and positive control group. The content of phenol red in the trachea of mice increased significantly， while ear swelling and inhibitory rate of ear swelling decreased significantly， with statistical significance （P＜0.05 or P＜0.01）. There was no statistical significance in each index of mice between powder group and positive control group （P＞0.05）. Compared with corresponding groups of F. cirrhosa， coughing latent period of mice prolonged significantly in F. unibracteata ethanol extract group （P＜0.05）， other indexes had no statistical significance（P＞0.05）. CONCLUSIONS： The antitussive， antiasthmatic， phlegm-resolving and anti-inflammatory effects of F. cirrhosa are similar to or worse than those of F. unibracteata.
