[Quantitative determination of ursolic acid in Herba cynomorii by ultraviolet spectrophotometry]
Abstract:
Ursolic acid was isolated form Herba Cynomorii by thin layer chromatography and was quantitatively determined by ultraviolet spectrophotometry. The results indicate that the content of ursolic acid is 0.78%. The average recovery rate of ursolic acid is 97.4%, RSD = 0.45% (n = 4).
