[Identification of the root of Punica granatum in galenic preparations using TLC]

The alkaloids present in the root of "Punica granatum" have been extracted by two different methods: extraction by Soxlet and extraction by steam distillation. Then the extracts have been compared by TLC chromatography using different solvents and specific chromogen reagents. The presence of pseudo-pelletierine has been confirmed in both the extractive solution by reaction with conc. K2Cr2O7. The above results explains the toxic activity of the unsuitable galenic preparations.
