ABSTRACT
This
research optimizes the process parameters for extracting oil from the kernels
of Azadirachta indica A. Juss using a ternary solvent mixture composed
of ethanol, n-hexane, and petroleum ether. Utilizing Soxhlet extraction, a
maximum neem seed oil yield of 51.57% was obtained using 36.76v/v % Petroleum Ether, 26.4 v/v% Ethanol and 36.98v/v%,
N-Hexane at 42.4 oC
over an extraction period of 6 h. The physicochemical characterizations
of the extracted oil revealed a specific gravity of 0.88 at 15 0C, kinematic viscosity of 29 mm2/s at 40
0C , acid value of 1.70
mg KOH /g,
iodine value of 76.6 g I₂/100 g,
saponification value of 203.5 mg/KOH/g, and moisture
content of 4.7%.
