To investigate biopharmaceutical and antifungal properties of pure and complexed ellagic acid. Caco-2 cells cultured in a Transwell inserts were infected with to develop an model. Ellagic acid was complexed with cyclodextrins. Microbial compositions, ellagic acid concentration as function of time and characterization studies of complexes were evaluated. Ellagic acid presented ability to reduce invasion, although this was not statistically significant. Its poor water solubility and absorption probably limited this ability. Water solubility was increased after complexation with hydroxypropyl-β-CD; however, ellagic acid/hydroxypropyl-β-CD did not improve the antifungal activity. Although ellagic acid presented a promising antifungal activity, its biopharmaceutical properties limit such activity and should be improved.

Parasitic diseases such as trypanosomiasis and leishmaniasis pose significant health challenges in Africa. The Senegalese Pharmacopoeia, known for its many medicinal plants with anti-infectious properties, can be a source of antiparasitic natural products. This study aimed to evaluate the in vitro antiparasitic activities of 33 methanolic extracts from 24 ethnopharmacologically selected plants against Trypanosoma brucei brucei and Leishmania mexicana mexicana, as well as their cytotoxic activities on WI-38 cells.

Objectives: The concept of beauty from within is a growing trend in the market and people now look for oral supplements that can enhance the well-being of skin from within. Within this principle, a proprietary pomegranate extract (Grantria), standardized to ellagic acid, punicic acid and punicalagin, was developed using ADOP (Advanced Oil-Powder) technology and was clinically evaluated for its efficacy and safety in healthy adults.
Methods: This evaluation was carried out as a randomized, placebo-controlled clinical study for 60 days at a daily dose of 300 mg.

Acetylcholinesterase (AChE) is widely recognized as a promising therapeutic target enzyme for Alzheimer's disease (AD). The screening of AChE inhibitors (AChEIs) holds great significance for the treatment of AD. In this study, cellulose filter paper (CFP) -immobilized AChE was prepared and firstly applied to screening AChEIs from 30 % ethanol extract of Phyllanthus emblica L.
