Abstract
Aims: This study was designed to compare the extractable yield of Chrysophyllum albidum seed oil, the phytoconstituents, and physicochemical parameters with the commercially available vegetable oil, to ascertain their suitability for human consumption and industrial uses.
 Place and Duration of Study: Biomedicinal Research Centre, Forestry Research Institute of Nigeria in collaboration with the Pharmaceutical Chemistry Laboratory, University of Ibadan, Oyo State, Nigeria, between October, 2018 to July, 2019.
 Methodology: The seeds were collected from two locations (a parent tree in the Forestry Research Institute of Nigeria (FRIN) and as well procured at Akesan market in Oyo town (Oyo) all in Oyo State, Nigeria. The experiments were executed adopting the standard procedures. The air-dried powdered C. albidum seed was cold macerated with analytical grade N-Hexane. The oils were purified using activated charcoal and qualitatively screened to ascertain the phytochemicals in them. Physico-chemical parameters were quantitatively determined following AOAC guidelines.
 Results: The results revealed that C. albidum is a low oil yielding seed especially when cold maceration was employed. The phytochemical screening revealed the presence of alkaloids, anthraquinones, terpenoids, and cardiac glycosides in all the oils. Saponins were found only in the oil from the FRIN source. While tannins and flavonoids were absent in all the oils. The physico-chemical parameters revealed the ranges of 0.90 - 9.45 mgKOH/g (Acid value), 101.90 - 356.60 mgKOH/g (saponification value), 65.30 - 78.00 mg/g (iodine value), 101.00 - 348.50 (ester value), 2.93 - 6.21 (PH value), 0.787 - 0.900g/cm3 (Relative density) and 1.4590 - 1.6560 (Refractive index @280C).
 Conclusion: It can be deduced that there are disparities in the yield, phytoconstituents and the physico-chemicals of the oils used for this study. Further research is needed on the C. albidum oil to validate its edibility and affirm its medicinal uses.
