摘要: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。

Abstract :Various P.quinquefolium species were analyzed polymorphologically by random amplified polymorphological DNA(RAPD)method. Most of random primers showed polymorphous.Fingerprints of real products of P.quinquefolium are considerably different from adulterants.Most of P.quinquefolium species have the similar fingerprints except three species from Shanxi Province.
