MEDICINAL HERBS AS REGULATORS OF PATHOGENIC MICROORGANISM ACTIVITIES

DJUKIC, D.,^[1] ANDIC, L., ^[2] KALINIC, S., ^[3] JURISIC, I. ^[4]

Synopsis

The paper studies the effect of extractive substances of medicinal herbs (sallow, sage, mint, chamomile, nettle and dog rose) on the growth of certain pathogenic microorganisms (Candida sp., Eschericia coli, Proteus sp., Salmonella sp., Bacillus subtilis, Streptococcus haemoliticus A, Staphylococcus aureus).

The data obtained show that the widest and strongest growth inhibition spectra were recorded in alcoholic extracts of mint and sage, respectively. A somewhat narrower and weaker spectrum was exhibited by alcoholic extracts of chamomile and nettle, followed by sallow and dog rose producing the narrowest and weakest spectrum of inhibitory effect. None of the treatments investigated affected Proteus sp. whereas the sage extract was the only one to have exhibited inhibitory effect on Bacillus subtilis. Aqueous extracts of the mentioned herbs did not directly inhibit either of the microorganisms investigated.

Key words: extracts, Teucrium montanum L., Salvia officinalis L., Mentha piperita L., Matricaria chamomilla L., Urtica dioica L., Rosa canina L., antimicrobial activity.

Sinopsis

LEKOVITE BILJKE KAO REGULATOR AKTIVNOSTI PATOGENIH MIKROORGANIZAMA

U radu je proučavan uticaj ekstraktivnih materija lekovitih biljaka (trava iva, žalfija, nana, kamilica, kopriva i šipurak) na razvoj nekih patogenih mikroorganizama (Candida sp., Eschericia coli, Proteus sp., Salmonella sp., Bacillus subtilis, Streptococcus haemoliticus A, Staphylococcus aureus).

Dobijeni podaci ukazuju da je najširi spektar inhibitornog dejstva ispoljio alkoholni ekstrakt nane, a najači alkoholni ekstrakt žalfije. Nešto uži i slabiji spektar inhibitornog dejstva ispoljili su alkoholni ekstrakti kamilice i koprive, još uži i slabiji kod trave ive, a najuži i najslabiji kod šipurka. Ni jedan od ispitivanih tretmana nije delovao na Proteus sp., dok je samo ekstrakt žalfije ispoljio inhibitorni efekat u odnosu na Bacillus subtilis. Vodeni ekstrakti pomenutih biljaka nisu direktno inhibirali ni jedan od ispitivanih mikroorganizama.
