This study aimed to investigate the inhibitory leverage of the aqueous and alcoholic extracts from Asparagus (Asparagus officinalis L.) root as in inhibiting inhibit the growth of the pathogenic bacterium, and fungus in vitro study. Concentrations of 50, 100, and 150 mg.ml-1 were used as aqueous extract and alcohol extract of Asparagus root against selected organisms, which tested using a drilling method, adding a 0.2 ml aqueous extract and alcohol extract of Asparagus root in every per well. Also 0.2 ml of distilled water and methanol alcoholic add as control and tetracycline as an antibiotic. GC/MS test results showed that the Asparagus root extract (ARE) contains various major phytochemical compounds such as flavonoids, phenols, alkaloids, glycosides, steroid, resin, saponins, and tannins. Also, it was observed that the alcoholic ARE had a higher inhibitory effect than aqueous ARE of Escherichia coli and Staphylococcus aureus. The highest diameter of inhibition at alcoholic extract concentrations of 50, 100 and 150 (mg.ml-1) were 28, 32, 35, and 26, 31, 35 mm respectively for aqueous ARE, compared to other concentrations. Whereas the effect of the aqueous extract was higher for the Pseudomonas 17, 25 and 34 mm compared to other concentrations, except for the antibiotic, which obtained the highest value (41mm). Aqueous extract concentrations 50, 100 and 150 mg.ml-1 showed higher efficiency than alcohol extract, antibiotic and control; when used against the fungus Aspergillus niger, and pathogenic yeast Candida albicans, the retarding diameters were 14, 17 and 23, and 11, 13 and 15 mm, respectively.
