This study compares the chemical constituents of extracts from the bark of Cinnamomum cassia obtained with the use of ionic liquids and organic solvents, as well as investigates their antifungal and yeasticidal activity. The type of ionic liquid was found to play a significant role in this process. We found that the ionic liquid tris (2-hydroxyethyl) methylammonium methylsulfate is a most efficient extracting agent, superior to classical solvents such as ethanol, ethyl acetate, hexane, dichloromethane. The obtained extract revealed high antimicrobial activity against yeasts, fungi pathogenic for plants and bees, dermatophytes, filamentous moulds with similar potencies as the standard fungicides.
