Abstract:- Comparative study on extraction of essential oils from Scent leaf (ocimumgratissimum) and Fluted Pumpkin leaf (telfairiaoccidentalis) using solvent extraction method have been investigated. The solvent used was ethanol. The yields for both leaves were 2.28% for Ocimumgratissimum and 2.14% for Telfairia Occidentalis respectively. The optimum temperature and time of extraction was 78oC and 180 minutes for both leaves. Ocimum Gratissimum gave a higher yield than Telfairia Occidentalis. Physical and chemical properties were assessed to evaluate quality characteristics of the oils. The results obtained for ocimumgratissimum and telfairiaoccidentalis are as follows: Saponification value, 154.3% and 112.2%, %FFA: 0.374% and 2.057%, Acid value: 0.187mg/g and 1.029mg/g, Peroxide value: 154.3% and 112.2%, Iodine value: 126g and 54.9g respectively. The result from the analysis of these essential oils have shown that they can be applied in vast industrial processes such as soap making due to their high saponification values.
