分光光度测定

The ultraviolet spectrophotometry method as determining the content ofsapogenins was used to evaluate the change of the quality in Dioscorea Zingiberensis C.H. Wright before or after supercritical CO_2 fluid extraction. The content of sapogeninswas 2.03% and 1.84% respectively in original and depurative sample, which showed thatdepuration of Cu, Cd, Pb in Dioscorea Zingiberensis C. H. Wright by supercritical CO_2fluid extraction had little influence on the active ingredient.
