AEPS (Ankleshwar Environmental Preservation Society) Institute of Science, Gujarat affiliated with Veer Narmad South Gujarat University, Surat In order to valorize non-edible seeds oil from some Cameroonians plants videlicet Acacia hockii (AH), Croton gratissimus (CG), Garcinia livingstonei (GL) and Moringa oleifera (MO), the production of biodiesel was undertaken. Two extraction methods were used. Production of FAMEs orbiodieselwas done using both acid and base catalyzed transesterification. For the soxhlet extraction the yields were 9.57, 7.72, 10.21 and 36.83% for AH, CG, GL, and MO, respectively, on the other hand the surfactant-assisted extraction yields were 3.0, 2.5, 7.3 and 33%, for AH, CG, GL and MO. Moreover, the acid catalyzed reaction gave a greater crude yield of 90% for all the four plants than the base catalyzed which gave, 87% (AH) and 50% (CG), 84% (GL) and 74% (MO). Focalizing on the kinematic viscosity 4.0, 4.23 and 5.22 mm 2 /s for BAH, BGL and BMO respectively. Testing the ignition abilities of the FAMEs, BGL and BAH ignites faster than BMO with low cetane number. The FAMEs had two characteristically strong absorption bands that identifies the ester functional groups. Hence the production of biodiesel from non-edible seed oils can alleviate to the plights of mankind. References 1. Alang M.B., Ndikontar M. K., Ndifon T and Yahya M.S.
