Abstract
Antimikrobna svojstva raznih prirodnih spojeva postaju zna ajno podru je istraživanja, ponajvibe zbog sve ve e rezistencije mikroorganizama na antibiotike koji su do sada bili u birokoj uporabi. ebnjak (Allium sativum) vrlo je cijenjen u kulinarstvu, no njegova ljekovita svojstva poznata su od davnina. Sadrži niz biolobki aktivnih spojeva, uklju uju i mnoge s antimikrobnim svojstvima. U ovom radu istražen je antimikrobni u inak razli itih ekstrakata doma eg i kupovnog/uvoznog ebnjaka... More (podrijetlom iz Kine) na patogene mikroorganizme prisutne u prirodnim vodama. Ekstrakti ebnjaka pripravljeni su u acetonu, etanolu, metanolu i ultra istoj vodi. Ekstrakt doma eg ebnjaka u acetonu pokazao je najbolje antimikrobno djelovanje i to na bakteriji Listerii monocytogenes. Na Gram(+)-bakterijama uo eno je izraženije antimikrobno djelovanje u odnosu na Gram(-)-bakterije. Bakterija Pseudomonas aeruginosa pokazala je najve u otpornost na ispitivane ekstrakte. Pomo u GCMS u gotovo svim su ekstraktima detektirani spojevi: dialil-sulfid, dialil-disulfid, metil-disulfid, dimetil-trisulfid, metil-alil-disuflid te sumpor Less
Abstract (english)
The antimicrobial properties of various natural compounds are becoming a significant area of research, mostly due to the growing resistance of microorganisms to antibiotics that have been widely used so far. Garlic (Allium sativum) is highly valued in cooking, however, its medicinal properties have been known since ancient times. It contains a number of biologically active compounds, including many with antimicrobial properties. In this paper, the antimicrobial effect of different... More extracts of home-grown and purchased/imported garlic (originating from China) on pathogenic microorganisms present in natural waters was investigated. Garlic extracts are prepared in acetone, ethanol, methanol and ultrapure water.The extract of home-grown garlic in acetone showed the best antimicrobial activity against Listeria monocytogenes. A more pronounced antimicrobial effect was observed on Gram(+)-bacteria compared to Gram(-)-bacteria. The bacterium Pseudomonas aeruginosa showed the highest resistance to the examined extracts. Using GC-MS, the following compounds were detected in almost all extracts: diallyl-sulfide, diallyl-disulfide, methyl-disulfide, dimethyl-trisulfide, methyl-allyl-disulfid and sulfur. Less
