RAPD Analysis of Pogostemon cablin from Different Habitats / 中药新药与临床药理

ABSTRACT

Objective To compare the genetic difference of Pogostemon cablin from different habitats.Methods Forty-six primers were used to analyze the fingerprint of Pogostemon cablin by Random Amplified Polymorphic DNA,and 6 of them were identifiable.Primer S358 could reflect the tiny polymorphic differences of Pogostemon cablin from different habitats which had 3 same amplified strips.Primers S358,S359,S443 could be used for the identification of Shipai sample from its other species.Results The results of cluster analysis showed that the two samples from Gaoyao were classified as one type,the four samples from Zhanjiang,Hainan,Shipai as another type,one sample from Caizhilin and one from the pharmacy of the First Affiliated Hospital of Guangzhou University of TCM as the the third type,and the sample from the Qingping Traditional Chinese Herbal Market as the fourth type.Conclusion The RAPD analysis can be used for the identification of Pogostemon cablin from different habitats.
