运用ＲＡＰＤ 技术对来自不同产地的西洋参样品进行多态性分析。结果显示， 大部分引物能扩增出清晰的ＤＮＡ 指纹图， 西洋参真伪品之间的指纹图谱差别较大， 而各地产西洋参ＤＮＡ 指纹图基本一致。同时，发现个别产地样品的指纹图有不同程度的改变， 考虑有变异可能。
Polymorphic analysis of American ginseng samples from different origins was conducted using RAPD technology. The results showed that most of the primers could amplify the clear DNA fingerprints, and the fingerprints of the American ginseng authenticity products were quite different. The fingerprints of the American native ginseng DNA were basically the same. At the same time, it was found that the fingerprints of samples from individual production sites were changed to varying degrees, considering the possibility of variation.
