Antimicrobial activities evaluated from leaves, flowers, fruits and latex of locally obtained Calotropis procera from Al-Sharifieya, Taif in different aqueous solutions and solvents such as sterilized Zamzam water and distilled water, ethanol, acetone, isoamyl alcohol and 100 mM Tris-HCl at pH 8.7 by using liquid Nitrogen. Calotropis procera was subjected to a standard agar well diffusion method. The ethyl alcohol extract of leaves of Calotropis procera showed an activity against both Pseudomonas aeruginosa ATCC 27853 and Candida albicans ATCC 10231 with a concentration of 200 mg/ml clearing zones 10 mm in diameter. The Tris-HCl at pH 8.9 (100 mM) extracts of leaves extracts also showed the highest antimicrobial activity against Pseudomonas aeruginosa ATCC 27853 with same concentrations (diameter 12 mm). The ethyl alcohol extracts of flower and latex showed antimicrobial activity against Bacillus subtilis ATCC 6633 with same concentrations (diameter 10 mm and 8 mm). Among the different solvent extracts of Calotropis procera, the distilled water and Zamzam water extracts of leaves, flower, fruit, latex and Tris-HCl pH 8.9 (100 mM) extracts of fruits and latex showed activity against Bacillus subtilis ATCC6633 with the same concentration (diameter 8 mm). Similar inhibitions (zones of 4-6 mm) for Zamzam and sterilized distilled water extracts of fruit of Calotropis procera were seen for the Escherichia coli ATCC 8739, Micrococcus luteus ATCC 9341 and Pseudomonas aeruginosa ATCC 27853. In isoamyl alcohol and acetone extracts of fruit activity was observed in all four bacteria
