[Random amplified polymorphic DNA analysis on Curcuma wenuujin and C. sichuanensis].
OBJECTIVE
To discuss the problem of classifying Curcuma for Medical purposes.


METHODS
RAPD was used to detect the DNA polymorphism within and among Curcuma wenyujin, C. sichuanensis and C. aromatica.


RESULTS
It is hard to differentiate between C. wenyujin and C. sichuanensis from the DNA level. The relationship between C. wenyujin and C. aromatica was also analyzed.


CONCLUSIONS
Based on the morphological and chemical data, it is suggested that these two species should be combined into one and that classification based on peduncle central or peduncle lateral may not be right. This method will help to some degree to solve the problem of certifying the medicinal plant Curcuma.
