Keywords: Medicinal plant, aromatic plants, antimicrobial activity |
Objective: Use of components derived from plant extracts
is rapidly increasing today, especially in the pharmaceutical
industry. In this study it is aimed to investigate the
antimicrobial and antifungal effects of extracts of medicinal
and aromatic plants such as lavender (Lavandula stoechas),
sage tea (Salvia officinalis), thyme (Thymus vulgaris) and
chamomile (Matricaria chamomilla).
Material and Methods: Antibacterial and antifungal
activities of extracts of these plants against gram-positive
(Staphylococcus aureus [ATCC 29213]), gram-negative
(Escherichia coli [ATCC 25922]) bacteria and yeasts as
Candida krusei (ATCC 6258), and Candida parapsilosis
(ATCC 22019). They were compared with vancomycin,
cefepime, levofloxacin as for antibacterial, and with
fluconazole as for antifungal agents.
Results: In our study, it was found that especially the extract
of the plant of the S. officinalis has activity against strains of
both gram (+) and gram (-) bacteria and yeasts.
Conclusion: All of the plant extracts used in the study were
found to be effective against S. aureus strains, while
lavender (L. stoechas) and chammomile (M. chamomilla)
plants were the most effective and thyme (T. vulgaris) plant
was the least. Likewise, all of these extracts were found to
be effective against E. coli, and M. chamomilla the
highest; and T. vulgaris plant, sage tea (S. officinalis)
and L. stoechas plants were found to be less effective in
decreasing order. Of the plant extracts, only S. officinalis
plant extract was effective against C. krusei, whereas
all of them were determined to be effective against
C. parapsilosis.
