目的 探讨同种不同产地牛蒡子 DNA指纹图谱特征。方法 采用 RAPD技术对全国四大商品区的中药牛蒡子生品和其中两个商品区的制品进行了 DNA指纹图谱特征研究。结果 四大商品区的生品牛蒡子 DNA指纹图谱一致,制品牛蒡子的 DNA指纹图谱与生品的有较大差异。结论 DNA指纹图谱用于鉴定同种药材的生品结果可靠。

Object To study the DNA fingerprinting of Arctium lappa L obtained from different localities.Methods DNA fingerprinting of samples of crude and processed A-lappa collected from four large commercial centers were examined by RAPD.Results All crude A-lappa showed similar fingerprinting characteristics, while the processed products gave considerable different results.Conclusion DNA fingerprinting study is a reliant method to differentiate crude A-lappa from its processed product
