In-Depth Information
Experiments showed antibiotic activity of acetone extracts from most of herbs
relatively to test organisms. All acetone extracts under study did not show any antibi-
otic activity relatively to Е. coli.
The gowth of golden staphylococcus ( S. aureus ) was inhibited by extracts of fl ow-
ers of Potentila recta L., Origanum vulgare L . , Fragaria vesca L., and Eryngium
planum L and by leaves of Glycyrrhiza uralensis L . and Filipendula ulmaria L.
Maximum zone of growth inhibition of St. aureus was found for acetone extract from
fl owers of Potentila recta : the diameter of zone of bacteria growth inhibition reached
13 mm (Table 12.3).
