Aim: To investigate the varietal difference in the composition of the oil of two Chryosophyllum albidium species. Study Design: Laboratory experimental design was used. Place and Duration of Study: Chryosophyllum acreanum and Chrysophyllum africana seed species of Chrysophyllum albidium were collected from Oja Oba market, Ibadan, Oyo State. The study was carried out between February 2019 - August 2019 at the Oilseed Laboratory of Federal Institute of Industrial Research, Oshodi, Lagos State, Nigeria. Methodology: Oil in both seeds was extracted using Soxhlet extraction method. The physical and chemical properties of the oils were determined using official methods of analysis while the fatty acid composition of the seed oils was analysed using Gas Chromatography- Mass Spectrophotometer. Results: The oil yield for both seeds was low, 3.52% for C. acreanum and 3.75% for C. africana. The values for the physical properties (Specific gravity, refractive index and unsaponifiable matter) of C. acreanum seed oil were higher than for C. africana seed oil. The chemical properties shows that the acid and peroxide values are 2.79mgKOH/g; 2.67mgKOH/g, 1.78mEq/kg; 1.63mEq/kg for C. acreanum and C. africana seed oil respectively while the iodine values for both seed oils are below 100mgI2/100g. The fatty acid composition shows that both seed oil contains myristic acid as their major fatty acid. Conclusion: The evaluated characteristics of the seed oils showed that there is no significant differences in the oil composition of C. albidium seed varieties as the oil composition are closely related except for the slight difference in their fatty acid profile.

Grape seeds from five known red grape sorts and two new local sorts, obtained by hybridization of red and white varieties, have been valorized as vegetal oils, through good yield extraction. The fatty acid content the of obtained oils was determined by GC-FID, as methyl esters, and directly by 1H-NMR spectroscopy. The obtained grape seed oils have a high content in linoleic acid (over 70%) and a relatively low quantity of saturated fatty acid (stearic and palmitic). Both measurement methods gave similar results confirming the accuracy of the spectroscopic method, which is less time and reagent consuming. Based on the fatty acid profile (FAP) of the oils, determined by either FT-IR or 1H-NMR and using the Principal Component Analysis (PCA) and Hierarchical Clustering Analysis (HCA) statistical methods, the discrimination between the classical known grape sorts and the new local varieties could be achieved. The results show that such method is appropriate for discovering possible adulteration of the grape oils, valuable products due to the essential unsaturated acid content.
