Abstract：Determination and analysis for the Scutellaria baicalensis Georgi with space mutagenesis and the ground group were carried out with FTIR for the first time in order to fully understand the quality changes of the 4th generation of space mutagenesis of Scutellaria baicalensis Georgi and do further research. The result shows that for the FTIR spectra of the two samples the position and shape of main absorption peaks are approximately the same, indicating that the major components and the structures of space group remain intact, but the intensities of the absorption peaks are obviously different, with the intensities of the space group significantly enhanced compared to the ground group, especially for the flavonoid compounds (baicalin, baicalein, wogonoside, wogonin and wogonoside etc), which are the main active components of the Scutellaria baicalensis Georgi, the absorption peak intensities at 3 391, 1 655 and 1 069 cm-1 are obviously stronger than those of the ground group, so the contents of flavonoid compounds and other components are higher, and the amorphous active components are optimized. Space mutation breeding is conducive to breeding new varieties of highly active components, and it is also one of the ways to innovate Chinese medicines germplasm resources efficiently.
