Abstract: The aim of current study is obtain oil from citrus-peels waste, and then exposure to chemical , physical and biological tests to achieve this goal , the percentage of oil extraction was 30% and that detecting process of phenols showed that oil contain phenols and the result was positive with ferric chloride detector by appearance the blue color and the quantity of whole phenols in oil was 40 (GAE. mg /g), and the PV for oil in concentration 50 ppm and 100 ppm was 5.8 and 5.5 respectively , when evaluation phenolic compounds in citrus peels oil by using HPLC and GC, the phenolic compounds was limonene , alpha penen and beta-penen with concentration 91.7%, 2.89% and 5.24% respectively , when evaluation antimicrobial activity for oil in concentration (0.5, 1, 2 and 3)%, the diameter of clear zone was 2,4,7 and 11 (mm) respectively against salmonella typhi bacteria and 5,10,14 and 13 (mm) respectively against staphylococcus aureus bacteria and 5,11,13 and 11 (mm) respectively against E.coli bacteria and 4 ,11 , 1 and 11 (mm) respectively against Bacillus subtillus bacteria and in same concentration the diameter of clear zone against Aspergillus niger mold was 4, 9, 15 and 12 (mm) respectively and 5,9,15 and 12 (mm) against candida albicans yeast, all them with differences on p(0.05), the minimum inhibition concentration to extracted
