The inhibition zones of the microor

The inhibition zones of the microorganisms sensitive to
the methanol extract were 1-15 mm, respectively (table
1). The highest inhibition zone (15 mm) was observed in
both Inula aucherana and Fumaria officinalis against
Staphylococcus aureus (table 1). Methanolic extract of
Fumaria officinalis had higher inhibition zone (14 mm)
than positive control (10 mm) against Cladosporium
herbarum. Methanolic extract of Alkanna tinctoria had
higher inhibition zone (10 mm) than positive control (7
mm) against Alcaligenes feacalis. Methanolic extract of
both Tribulus terestris and Polygonatum multiflorum had
higher inhibition zone (10 and 11 mm) than positive
control (7 mm) against Alcaligenes feacalis (table 2).
These results are of interest since they have been obtained
with methanol extracts and are not a pure product and it
could be considered to have a good potency level.
Based on these results, it is possible to conclude that
methanolic extracts of Inula aucherana, Fumaria
officinalis, Crocus sativus, Vicum album, Tribulus
terestris, Polygonatum multiflorum, Alkanna tinctoria and
Taraxacum officinale had different level antioxidant and
antimicrobial activity. The obtained results might be
considered sufficient to further studies for the isolation and
identification of the active principles and to evaluate of
possible synergism among extract components for their
antioxidant and antimicrobial activity. Investigations are in
progress to determine the degree of toxicity of these
extracts.
