The present work was carried out to obtain essential oil from the sour orange peel (Citrus aurantium) which is rich in essential oil through steam distillation. Extraction using distilled water was the control treatment and other treatments were carried out by using 3%, 5%, and 7% NaHCO3. This study determined the yield% of essential oil in four different treatments in freshly extracted essential oil. The Physico-chemical properties of essential oil were determined in freshly extracted essential oil .In performance, T3 (5% NaHCO3) was the best yield% (w/w) with a value of 3.15%. According to this study, using NaHCO3 for essential oil extraction from sour orange peel resulted in a higher essential oil yield than distilled water. The extracted essential oil in sour orange peel has distinct pale yellowish color with a fresh and tangy smell. T3 exhibited that distinct color and odor. Based on the yield% and Physico-chemical analysis, the essential oil extraction using 5% NaHCO3 was the best treatments followed by treatment 4 (7% NaHCO3), treatment 2 (3% NaHCO3) and treatment 1.
