Comparison of analytical methods of determining saponins in some araliaceae species


, : Comparison of analytical methods of determining saponins in some araliaceae species. Herba Polonica 32(1): 39-46

Methods of determining saponins in Panax ginseng, Aralia mandshurica and Hedera helix and their specimens are presented. The saponins from the leaves of H. helix and roots of A. mandshurica after acid hydrolysis were determined by densitometric, colorimetric and gas chromatographic methods. The difference range of the results obtained after the application of these methods was aroung 10%. Ginsenosides from the roots of P. ginseng and in specimens from them were determined by densitometry and colorimetry. The results obtained with the densitometric method were lower than the results obtained with the colorimetric method. However, the results obtained for P. ginseng and P. vietnamensis with these two methods were very close.

The 25-kDa core domain of the tumor suppressor p53 is inherently unstable and melts at just above body temperature, which makes it susceptible to oncogenic mutations that inactivate it by lowering its stability. We determined its structure in solu...
