Depending on composition, fatty acids of plant sources are explicitly useful in food, chemical and pharmaceutical industries. The present study characterizes Soxhlet extracted neem seed oil by determination of physicochemical properties and bioactive compounds. Extraction involved the use of solvent semi-continuous extraction method for 6 hours with N-hexane. Percentage Oil yield was at 39. Saponification value (50.490mgKOH/g), Iodine value (50.28g/100g), Acid value (5.610mgKOH/g), Free fatty acid (2.805w/w), Peroxide value (62.75meq/kg) and Specific gravity (0.948) were determined. Density at 250C, Flash point, boiling point, melting point, colour and Odour provided supportive information to the major physicochemical properties analyzed. Gas Chromatography - Mass Spectrometry (GC-MS) of the Soxhlet extracted Neem Seed oil showed different peak values of industrially essential compounds such as 7-Pentadecyne, Glycidyl palmitate, Oleic Acid, 9,12-Octadecadienoic acid and methyl ester (Omega-6 acid). Saponification value was found to be high, suggesting the presence of FFA with low molecular weight, which brands the oil as essential in cosmetic and food industries. Low Iodine value and low total acidity seems to consolidate the usefulness of neem seed oil in cosmetic industries. Conversely, the high peroxide level makes it unsuitable for cooking. It may therefore be inferred that Soxhlet extracted Azadirachta indica seed may be industrially viable but less suitable for consumption.

Background: Azadirachta indica (neem) seed oil was evaluated for its hepatoprotective effect. Liver damage was induced using carbon tetrachloride (CCl4) while silymarin served as a positive control.Aim: This study is aimed at testing the hepatoprotective potentials of A. indica seed oil on Wistar rats.Method: Hepatotoxicity was induced by the administration of 1.0 mL/kg of CCl4 subcutaneously to 72 healthy Wistar rats of both sexes (weight range: 145 g – 315 g). The seed oil of A. indica was orally administered daily in various doses of 0.25 mL/kg, 0.5 mL/kg and 1.0 mL/kg for 14 days. Animal body and organ weights were recorded, while blood and liver tissues were collected for biochemical, haematological and histological analyses.Results: Treatment with neem seed oil lowered the aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase levels significantly (P < 0.05) in a dose-dependent manner compared to the control. The haematological parameters, organ weight index and animal body weight showed no significant difference (P > 0.05) when compared with the control. Histology assessment was in agreement with the biochemical result as tissues of CCl4 exhibited significant fatty tissue accumulation, as opposed to that of 0.25 mL/kg neem treatment, which showed only moderate accumulation of fatty tissues, while higher doses, 0.5 mL/kg and 1.0 mL/kg, showed a healthy liver as compared with the control.Conclusion: The result of this study revealed that neem seed oil had a dose-dependent hepatoprotective effect on the experimental rats.
