Extraction and Comparative Evaluation on the Physicochemical Characteristics of Yemeni Moringa oleifera Seeds Oil
Moringa oleifera is a versatile tree with nutritional, medicinal and environmental benefits making it a valuable resource for communities in many regions of the world. This study aimed to extracted oil from Yemeni Moringa oleifera seeds oil (YMOSO) using two methods (cold pressing and seoxhlet n-hexane). The yields of the oils were 16.12% and 28.34, % respectively. The yields of the oils were 16.12% % and 28.34% respectively. Where it was investigate the chemical and physical characteristics by two method cold press and soxhlet n-hexane showed of Yemeni Moringa oleifera seeds oil (YMOSO), including a free fatty acid (FFA) content of 1.12 % and 2.98 %, an acid value of 5.99±0.5 mg/g and 6.52±0.5 mg/g, an iodine value of 67.68±0.1 mg/g and 67.43±0.1 mg/g, a saponification value of 189.51±0.1 mg/g and 188.49±0.1 mg/g, a refractive index of 1.46±0.01 and 1.47±0.01 at 25 °,C a moisture content of 0.24±0.03% and 0.36±0.03%, a density of 0.90±0.05 g/ml and 0.89±0.05 g/ml at 25 °C, a specific gravity of 0.968±0.03 g/ml and 0.956±0.03 g/ml at 25 °C, and a viscosity of 48 and 47 cP at 25 °C respectively. the chemical components of the oil were determined using Fourier transform infrared (FTIR) spectroscopy and Gas Chromatography-Mass Spectroscopy (GS-MS).
