摘要： A process for the preparation of spermicidal agents and other biologically active materials from neem oil or extractives by subjecting a neem feed obtained from neem oil to the step of enrichment. Such a step of enrichment is carried out in a chromatographic column containing a sorbant, and the feed is eluted with a non polar followed by a polar solvent or mixtures thereof. In accordance with one embodiment, the feed is formed by subjecting neem oil to the step of solvent partition, the precipitate being removed therefrom and the filterate forming the feed. In accordance with another embodiment, the feed is formed by adding a polar solvent to the filterate of the first embodiment, the lower layer formed therefrom being subjected to the step of distillation for removal of the solvent to obtain a feed.

摘要： Nouveaux dispositifs de libération régulée de matières actives, notamment de produits pharmaceutiques, composés d'au moins deux parties s'interpénétrant. La partie mâle gonfle au contact de l'eau pour dégager la partie femelle. La partie femelle est de préférence faite d'une matière thermoplastique, par exemple LDPE, ou d'une matière soluble telle que la gélatine rendue imperméable par un revêtement extérieur en matière hydrophobe tel que le PVC. Les dispositifs trouvent une application particulière en tant que formes de dosage utilisées chez l'homme.
