Abstract

This research aims to know the viability of alcoholic extract of Ekbr Iraqi on the inhibition of growth of three kinds of yeasts isolated from fruit juices damaged the Candida tropicalis and Debaryomyces hansenii and Pichia tropicalis. Results showed that the focus damper minimum (Minimum Inhibition Concentration - MIC) to extract alcohol for Ekbr was 0.1 , 0.4, 0.1 mg / ml to the yeast Candida tropicalis and Debaryomyces hansenii and Pichia tropicalis, respectively, in orange juice, 0.4, 0.8, 0.2 mg / ml, respectively, in apple juice, while the focus was damper minimum (MIC) of sodium benzoate has reached 40, 160.80 micrograms / ml, respectively, in orange juice and 320 640 320 micrograms / ml, respectively, in apple juice. results show that disclosure of the chemical qualitative contain Propolis on resins (Resins) and flavonoids (Flavonoids) and phenols (Phenoles) as components of an effective .
