Biodiesel is derived from triglycerides by transesterification reaction with alcohol (ethanol or methanol), and has classified as a renewable, biodegradable, and nontoxic fuel. Several methods for biodiesel production have been developed, among which transesterification using alkali-catalysis gives high levels of conversion of triglycerides to their corresponding methyl esters in short reaction times. This study was conducted to extract the neem and Jatropha oil for the production of biodiesel using alkali-catalyzed reaction The samples were subjected to reaction with sodium hydroxide (NaOH), 0.2:1 w/v methanol (MeOH) to oil mole ratio, reaction temperature of 6°C, and 30 min reaction time. The final biodiesel yield obtained was 47.5% and 45.5% from the neem and the jaropha oil sample respectively. The basic physicochemical properties of the jatropha methyl ester produced from both jatropha oil samples were found to be within the ASTM D6751 specified limits.

is used in the treatment of diabetes mellitus, hypertension, dysentery, diseases of the kidneys, urinary and respiratory tract infections. 7, 9 Previous studies conducted on Ficus asperifolia showed that it possesses gastroprotective, 10 uterotonic, 11 hypoglycaemic 12 and hypolipidaemic properties. 13 The leaves of the plant have been found to possess antioxidant activities 14 as well as ameliorative effects against testicular problems. 8 Essential oils obtained from Ficus asperifolia were found to possess antimicrobial properties 15 and according to Watcho et al., 16 the fruit extracts possess androgenic-like activities. However, there are relatively scarce reports on the antiinflammatory or analgesic properties of the plant despite its wide usage in ethno-medicine against inflammatory diseases and pain management. This study, therefore, was aimed at evaluating the antiinflammatory and analgesic activities of methanol leaf extract of Ficus asperifolia on mice and rats.
