Abstract:
This study was aimed to compare the expectorant and antitussive actions ofPlatycodon grandilforum from different production areas in order to provide references for its cultivation and production. The antitussive activities ofP. grandilforum water extract from different areas were investigated through testing the cough times induced by ammonium hydroxide in mice. And the expectorant activities were studied by testing the amount of tracheal phenolsulfonphthalein excretion in mice. The results showed that the minimum effective dose ofP. grandiflorum fromChifeng of Inner Mongolia was 0.2 g·kg-1. Under this dosage,P. grandiflorum fromChifeng of Inner Mongolia can significantly reduce the cough frequency in mice (P < 0.01), and significantly prolong the cough incubation period in mice (P < 0.01).P. grandiflorum fromSichuan province,Shangzhou ofShaanxi province andChongqing can significantly decrease the cough frequency in mice (P < 0.05). P. grandiflorum from Sichuan province,Shangzhou ofShaanxi province andChifeng of Inner Mongolia can significantly increase the phenolsulfonphthalein excretion quantity in mice (P < 0.05). It was concluded thatP. grandilforum was effective for relieving cough and removing sputum. The effect ofP. grandilforum fromChifeng of Inner Mongolia was obviously stronger than that from other areas.
