摘要：
Gastrodia tuber and its component gastrodin have many pharmacological effects. The chemical fingerprints and gastrodin contents of eight Gastrodia populations were determined, and the genomic DNA polymorphism of the populations was investigated. Genetic distance coefficients among the populations were calculated using the DNA polymorphism data. A dendrogram of the genetic similarities between the populations was constructed using the genetic distance coefficients. The results indicated that the genomic DNA of Gastrodia tubers was highly polymorphic; the eight populations clustered into three m...
