Study of the impact of cyclodextrins on the solubility of vit EChl

In this work we have set as an objective the improvement of the conservation of the sperm of some species namely: Bovine avian and rabbit this through an intermediate objective; the improvement of the solubility of vitamin E and cholesterol in aqueous medium. For this purpose we prepared several complexes that we characterized by IR and DRX and that we applied to a cellular model (spermatozoon). The results obtained show that we were able to improve the solubility of vitamin E and cholesterol using cyclodextrins and PEG 6000 on the one hand and to discover a synergistic effect between vitamin E and cholesterol in their complexed and dispersed forms on sperm conservation on the other hand.
