Development and stability evaluation of an emulsified system containing Stryphnodendron adstringens (Mart) Coville (Fabaceae) extract from the Brazilian Cerrado

Abstract

Brazilian flora biodiversity is object of study and research of medicinal plants with healing and emollient therapeutic potential. On this basis, Stryphnodendron adstringens (Mart) Coville stands out and was the aim for the development and stability evaluation of an emulsified system. The formulation was prepared, bottled in plastic and glass containers and stored at room temperature, refrigerator and incubator. The accelerated stability test was carried out at T0, T15 days, T30 days and T60 days. And a microbiological analysis in accordance with the Brazilian Pharmacopoeia 5th was also performed. Results evidenced that the formulation remained stable during the evaluated period, especially at a refrigerated environment and bottled in glass container. Regarding microbiological aspects, no microorganism’s growth was observed, meeting quality standards. Accordingly, results will serve as a subsidy for study continuity and definition of the formulation validity period.
