Abstract: This paper studied the antimicrobial characteristics of extracts from Sabina vulgaris Ant bark with ethanol. The results indicated that the extract of a certain concentration can inhibit the growth of bacteria. That was: Bacillus subtilis: MIC 0. 25%, MBC 0.5%, Staphylococcus aureus: MIC 0.125%, MBC 0.125%, Escherichia coli: MIC 0.0625%, MBC 0.125%, Bacillus thruingiensis: MIC 0.125%, MBC 0.25%, Proteus vulgaris: MIC 0. 0625%, MBC 0.125%, Enterobacter aerogenes: MIC 0.03125%, MBC 0.125%. Extract of Sabina vulgaris Ant was also studied for its stability to temperature, ultraviolet and metal ions.
