Aqueous extract from urucum ( L.): antimicrobial, antioxidant, and healing activity.

Annatto was obtained from seed (urucum) and is commonly used in food and cosmetic industries. The objective of this study was to identify the antimicrobial and antioxidant activity of the aqueous extract from urucum seeds and its skin healing potential in exposed cutaneous lesions in rats treated with the gel containing the extract. Three types of extracts from seeds were made using chloroform, sodium hydroxide, water, and estimated bixin and norbixin.
