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).
