目的 为了探讨道地药材与非道地药材之间遗传变异的大小,并建立道地药材的品质鉴定方法。方法 运用了随机扩增多态DNA(RAPD)技术,对福建、江西、四川产的泽泻科植物泽泻Alismaorientalis进行了研究。结果 同种异地药材所形成的不同的居群,具有不同的遗传特征。结论 RAPD技术可作为鉴别道地药材的参考方法。

[Abstract]
Object<\b> To research genovariations between genuine Chinese herbs and non genuine ones and to develop a valuable tool used in identification of the Chinese herb.Methods<\b> RAPD technique was applied in studies on the samples of Alisma orientalis (Sam.) Juzep.from different area in Fujian, Sichuan and Jiangxi provinces.Results<\b> The DNA fingerprints of genuine and non genuine Chinese herbs were compared and it was suggested that the herbal populations growing in different area in above three provinces had different genus characteristics.Conclusion<\b> RAPD technique is a valuable tool for identification of genuine Chinese herbs.
