Essential oil such as limonene is found in abundance in citrus plants but there are limitations in its industrial production with respect to its yield, purity, safety and grade. Such problems could be circumvented by some alternative methods of extraction. Non- edible portion such as peels of citrus fruits, orange, lemon, sweet lime, pomelo and leaves of eucalyptus, lemon grass was used in this study. Various techniques such as soxhlet, rotary shaker, sonication and clevenger were used to extract the limonene content and analysis was done by Gas Chromatography (GC) technique. Limonene was found to be present in significant amount in all the samples with highest yield in orange, nutmeg and eucalyptus i.e. 347.21mg/g, 330.58mg/g and 250.99mg/g respectively. Sonication was found to be advantageous over the other methods due to its higher yield, less time of extraction and with reduced usage of organic solvent
