【摘要】 目的　比较四川南充与有关产地半夏的祛痰镇咳作用 ,为半夏的规范化种植和进一步开发利用提供依据。方法　祛痰实验用小鼠呼吸道酚红冲洗法 ,镇咳实验用氨水引咳法。结果　在祛痰实验中 ,半夏水、醇提取物口服给药均未见明显祛痰作用 ,与对照组比较差异无显著性 ;在镇咳实验中 ,所有半夏样品的水、醇提取物均可使咳嗽潜伏期延长 ,咳嗽次数减少 ,与对照组比较差异有显著性 ,并呈现良好的时-效关系。结论　四川南充与有关产地半夏均未见明显祛痰作用 ,而均有明显镇咳作用。就镇咳作用而言 ,水提物明显强于醇提物 ,野生半夏明显优于栽培半夏 ,其中尤以四川南充、广安、遂宁、凉山、甘肃西和的野生半夏样品镇咳作用较强更多还原

【Abstract】 Aim To Compare the quality of Pinellia Tubers between Nanchong Sichuan and relevant areas in order to standardize plant and to provide evidence for further exploitation and application. Methods Expectorant experiment was conducted with methods of washing mice’s respiratory tract with phenol red and antitussive effect, with ammomia caused mice cough. Results In the experiment of expectorant effect, oral administration of the water or the ethanol extracts of pinellia Tubers showed no obvious expectorant effect, it also showed no significant difference compared with control NS. In the antitussive effect experiment, however the water or the ethanol extracts of pinellia Tuhers prolonged the incubation period and reduced the frequency of coughing. It presented significant difference compared with the control NS and clear time-effect relationship. Conclusion Pinellia Tubers from Nanchong Sichuan and relevant areas showed no apparent expectorant effect and have destinct antitussive effect. As for antitussive effects, water extracts were stronger than those of ethanol extracts, and wild Pinellia Tubers outmatched planted ones. Antitussive effect of wild Pinellia Tubers samples was rather stronger from Nanchong, Guangan, Suining, and Liangshan of Sichuan and Xihe Gansu.更多还原
