Mineral Composition and Antimicrobial Activity of Ethanol Extract Birdsfoot Trefoil

Abstract

In order to study and find plant species that possess antimicrobial activity, this work was carried out testing of plant species Lotus corniculatus L. (birdsfoot trefoil). The work was conceived with the aim to determine the mineral composition and antimicrobial activity of ethanol extract birdsfoot trefoil, and in terms of potential use in food production. The minimum inhibitir concentration (MIC) was tested in microdilution method in a function of time of the extract and the growth of microorganisms. From the point of antimicrobial activity, by testing it was found that extract of Lotus corniculatus L. manifest the strongest antimicrobial activity against Escherichia coli, and the lowest to the bacterium Proteus hauser. Mineral composition of the extract plant species Lotus corniculatus L. was determined by ICP-MS. The study showed that the extract birdsfoot trefoil is rich by mineral composition.

Rad je koncipiran sa ciljem da se utvrdi mineralni sastav i antimikrobna aktivnost etanolskog ekstrakta žutog zvezdana, a u smislu potencijalne upotrebe u proizvodnji hrane. Minimalna inhibitorna koncentracija (MIC) ispitivana je mikrodilucionom metodom u funkciji ekstrakta i vremena razvoja mikroorganizama. Sa stanovišta antimikrobnog delovanja, ispitivanjem je ustanovljeno da ekstrakt biljke Lotus corniculatus L. ispoljava najjaču antimikrobnu aktivnost u odnosu na bakteriju Escherichia coli, a najmanju u odnosu na bakteriju Proteus hauseri. Mineralni sastav ekstrakta biljne vrste Lotus corniculatus L. određen je primenom metode ICP-MS. Ispitivanje je pokazalo da je ekstrakt žutog zvezdana bogatog mineralnog sastava.
