The isolation of rough lemon (Citrus jambhiri Lush) rind essential oil has been done by using hydrodistillation method and paper disk diffusion test for antibacterial activity test. 2.3 gram (1.51%) of essential oil was obtained from 450 gram of dried rough lemon rind powder. Based on the analysis using GC-MS, the essential oil from rough lemon rind contains 5 chemical compounds, but only 4 of them can be interpreted. They are Limonene (71.88%), 1,4-cyclohexadiene (13.93%), β-Pinene (10.57%) and β-Ocimene (2.37%). Antibacterial activity was tested to Bacillus cereus and Escherichia coli at 40% concentration (v/v) with 12.7 mm and 12.9 mm of clear zones respectively.
