The difference of ingredients between the roots from the SP1 plants of Achyranthes Bidentata carried by satellite and the control's were evaluated in this study. The techniques of ultraviolet-visible spectroscopy (UVS), infrared spectroscopy (IR), Xray diffraction (XRD) and SDS-PAGE were used to analyse the chemical constituent in the root of A. bidentata. The results demonstrated that the UVS, IR, XRD and protein fingerprints of the roots from A. bidentata were distinct with special characters. The difference of the IR, XRD and protein fingerprints could be discriminated the satellite plants roots from those of the control, however, there were no difference of the UVS fingerprints between the satellite plants roots and the control. This indicated that the kinds of chemical ingredients were not different between the two groups, but the contents of some chemical ingredients deceased in SP1 plants of A. bidentata carried by satellite.
