Abstract: The assay was aimed to investigate the effects of Zhike Pingchuan granules on expectorant, antitussive and antiasthmatic by animals experiment.Capillary method was used to observe the expectorant effect in rat,the cough model induced by strong ammonia in mice was used to observe the antitussive effect,asthma model induced by spraying method was used to observe the antiasthmatic effect.The results showed that the low dosage group of Zhike Pingchuan granules significantly increased excretion of trachea quantity compared with the blank control group (P＜0.05),and there were extremely significant differences between the blank control group and middle,high dosage groups (P＜0.01);the three high,middle and low dosage groups of Zhike Pingchuan granules extremely significantly prolonged the latent period of cough and decreased the frequency of cough induced by strong ammonia compared with the blank control group (P＜0.01); the low dosage group of Zhike Pingchuan granules had not significantly prolonged the latent period of asthma induced by 4% acetylcholine chloride compared with the blank control group (P＞0.05),and middle and high dosage groups had extremely significant difference compared with the blank control group (P＜0.01).Zhike Pingchuan granules had the effects of expectorant,antitussive and antiasthmatic.
