摘要：

The chemical composition of extract from the barks of cinnamon (Cinnamomum zeylanicum Nees) produced by extraction with 1,1,1,2-tetrafluoroethane was analyzed using GC and GC-MS. The main compounds (concentration higher than 3 %) of extract were: cinnamal (77.3 %) and coumarin (4.3 %). The studied extract demonstrated antimicrobial activity against pathogenic and spoilage microorganisms from clinical and food isolates belonging to species Staphylococcus aureus, Staphylococcus epidermidis, Salmonella abony, Escherichia coli and Candida albicans. The extract was inactive against some of the most resistible bacteria belonging to genus Pseudomonas. The produced cinnamon extract demonstrated higher antioxidant activity against DPPH radical in comparison with other plant extracts produced by low temperature extraction with tetrafluorethane.
