Abstract:Objective: Chemically modify by acetylation, Arracacia xanthorrhiza starch, and to physicochemically and pharmacotechnically characterize it, thereby evaluating its potential as a pharmaceutical excipient, in comparison with the native starch of Arracacia xanthorrhiza.Methods: The chemical modification was performed through acetylation with acetic anhydride (AA) on different levels, determining following starch's characteristics: degree of substitution (DS), size and form of particles, its degree of crystallin… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
