Seasonal chemical evaluation of Miconia chamissois Naudin from Brazilian Savanna

Miconia chamissois Naudin is a species from the Cerrado, which is being increasingly researched for its therapeutic potential. The aim of this study was to obtain a standardized extract and to evaluate seasonal chemical variations. Seven batches of aqueous extracts from leaves were produced for the standardization. These extracts were evaluated for total solids, polyphenol (TPC) and flavonoid content (TFC), vit...

Lycorine alkaloid and Crinum americanum L. (Amaryllidaceae) extracts display an...

Candida species are the main fungal agents causing infectious conditions in hospital patients. The development of new drugs with antifungal potential, increased efficacy, and reduced toxicity is essential to face the challenge of fungal resistance to standard treatments. The aim of this study is to evaluate the in vitro antifungal effects of two crude extracts of Crinum americanum L., a rich alkaloid fraction a...

Biological properties and phytochemical characterization from Miconia chamissoi...

The objective of this study was to evaluate biological and phytochemical properties of the aqueous extract from the leaves of Miconia chamissoisNaudin (AEMC). Phytochemical properties were assessed by analyzing the chromatographic profile and the polyphenol content of AEMC. Biological properties evaluation wasconducted based on cytotoxicity assay and by evaluating the antioxidant, antimicrobial, and enzymatic i...
