Definitions
- the present invention relates to a process for extracting a compound, NN 'DIBENZYLTHIOUREE from the root of a plant in the family of PENTADIPLANDRACEES, genus PENTADIPLANDRA BRAZZEANA, variety BRAZZEANA This plant is a liana which is found in Central African forests.
- the extraction process linked to the present invention makes it possible to isolate NN 'DIBENZYLTHIOUREE.
- 1kg of crushed and dried roots are put in a 2-liter yellow bottle.
- 1 liter of 95% ethyl alcohol is added as a solvent.
- This stoppered bottle is mounted on a mechanical shaker, the apparatus is left to shake the bottle for 4 hours to extract the compound well.
- the device is stopped and the bottle is left to stand for 1 hour.
- the lemon yellow filtrate is filtered and collected.
- the alcohol is removed by vacuum distillation at approximately 15 mm HG in a rotary evaporator in a water bath Thermostat set at 40 °. Avoid reaching a dry residue.
- NN 'DIBENZYLTHIOUREE the concentrated alcoholic solution is placed in a separatory funnel into which 250 ml of carbon TETRACHLORIDE are introduced, and the mixture is stirred by hand for 1 hour. At rest, 2 phases appear in the separating funnel. The hydroalcoholic phase contains the NN 'DIBENZYLTHIOUREE, which is not soluble in Carbon TETRACHLORIDE
- This method is based on the degradation of deoxyribose by free radicals generated by the xanthine / xanthine oxidase system. This degradation leads to the formation of malondialdehyde which is dosed by colorimetry. In this technique, the scavenging effect of free hydroxyl radicals results in a reduction in the formation of malondiadehyde.
