Abstract

Selon une variante du brevet principal, le dérivé disodique de la naringine est obtenu par addition à une solution alcoolique de naringine non plus de sodium métallique en solution dans l'éthanol mais d'une soude alcoolique, par exemple de soude éthanolique titrant environ 7 % en NaOH. On obtient des rendements quasi-quantitatifs sans risques dus à la manipulation de sodium.
