Chemical characterization and antimicrobial activity of Blumenbachia insignis (Loasaceae) native to South America

Abstract

Total phenolic content The total phenolic content in B. insignis was determined in extracts from flowers, fruits, leaves, roots, and stems (Table 1). The contents vary widely, ranging from 12.8 to 85.2 mg GAE/g extract. Flower extract presents a higher content of polyphenols (p < 0.05) with values of 85.2 mg GAE/g, while leaf extract presents 30.1 mg GAE/g and root extract shows 24.1 mg GAE/g. The samples obtained from fruit show the content of polyphenols of 12.8 mg GAE/g, while stem extract shows values of 15.2 mg GAE/g.
