Antimicrobial activity of petroleum ether extracts from leaves, seeds and roots of Zygophyllum fabago L. towards some microorganisms

Abstract

The  study  was  aims  to  evaluate  the  antimicrobial  acttvtty  of petroleum  ether extracts from  leaves , seeds and root of Zygophyllum fabago   , against   several   microorganisms  including   gram   negative bacteria (Pseudomonas aeruginosa  & Escherichia coli), gram positive bacteria  (Staphylluwccus aureus  & Bacillus  subtilis),  in addition  to yeast (Candida  albicans).

While the results of sensitivity of the microorganisms to words petroleum  ether extracts  showed different activity , petrolewn  ether extract of seeds showed  more antimicrobial activity compared to the other extracts , followed by leaves and roots extracts.

Concerning the bacterial  isolates B. subtilis was more sensitive, its growth  inhibited  by leaves, seeds and roots extract  of Z. fabago,  MIC

was  ( IOd·20)   mgfml,  followed  by S.  aureus  MIC  was  (20d  30) mgfml,  then  E. coli  was (30·10·50)  mgjml,  where as  P. acruginosa MIC was (50·20·30)  mg/ml. finally C. albicans which was the most resistant for all extracts (leaves, seeds, roots) and MIC was (50•20•30) mgfml.

Analysis of  petrolewn ether extracts from leaves, seeds and  root

from  Z.  fabago  was  carried  out  to  detennine   its  contents  from terpenoid compounds.
