Abstract：The outer space Saposhnikovia divaricata of the fourth generation was studied and compared with the ground group and comparison group for the first time. The intensity of carbonyl absorption peak at 1 640 cm-1 is stronger than the other two, indicating that chromone content was enhanced obviously. The peaks at 2 927 and 2 856 cm-1 were assigned to —CH2— groups, the peak at 1 050 cm-1 was due to the C—O groups, and the intensities at 2 927, 2 856 and 1 050 cm-1 were stronger than other samples, indicating that polysaccharide and glycoside contents were enhanced obviously. The intensity of lactone absorption peak at 1 743 cm-1 was stronger than the ground group and weaker than the comparison, indicating that coumarin content was higher than ground group and lower than the comparison. The major components and the structures remained intact，and the effective component contents were enhanced in the outer space Saposhnikovia divaricata. Using FTIR can analyse and characterize the intrinsic quality of the outer space medicinal materials.
