In this research, swainsonine contents of three Oxytropis species were determined by the high performance liquid chromatography coupled to mass spectrometry. The population genetic diversity was also studied and the swainsonine related molecular markers were screened by ISSR. In vitro fungi cultures from the individual plant of O. glabra were performed and microbiological morphology of the colony and the conidiophore were investigated. The 5.8S rDNA/ITS sequences of fungi amplified from total DNA in both plants and fungal endophytes were studied. These sequences were analysed and compared, and they were also compared to the 5.8S rDNA/ITS sequence of fungal enduphyte Embellisia sp. L12 from the O.lambertii, O.sericea and A.mollisimus distributed in USA.
