The phytochemical and physico-chemical properties of the seed and seed oil of Perseagratissima miller and Chrysophyllumalbidumg. Don.

Abstract

Phytochemical and physico-chemical properties of the seed and seed oil of  Perseagratissima and Chrysoplylumalbidum, were assessed by standard methods. Phytochemical analyses of Perseagratissima lipid extract showed the presence of alkaloids, saponins, tannins, steroid and peroxides. Equally, the analyses of Chrysophyllumalbidum showed the presence of alkaloids, saponins, terpenes,  steroids and peroxides. The physicochemical properties of the seed oil of  Perseagratissima revealed a saponification value of 194.6 (mgKoHg^–1 oil), unsaponification matter of 1.16%, an acid value of 6.5 (mgKoHg^–1 oil), acetyl value of 5.5 (mgKoHg^–1 oil), ester value of 188.1 (mgKoHg^–1 oil), viscosity of7.049 x 10-4 (kgm^–1S^–1), solidification point of 15.025° c, melting point of 160.9°c and pH of 7.05 at 30°c while those of Chrysophyllum showed asaponification value of 168 (mgKoHg^–1 oil), unsaponification matter of 6.6%, an acid value of 2.5 (mgKoHg^–1 oil), Acetyl value of 1.0 (mgKoHg¹ oil), Ester value of 165.5 (mgKoHg¹ oil),  viscosity of 2.403 x 10^-3 (kgm^-15¹), solidification point of 15.1°c, melting point of 140°c and pH of 8.0 at30°c. With these bioactive and physico-chemical properties, the seeds oil of P. gratissima and C. albidum have great potentials to be used in  pharmaceuticals and in medicines and as well industrial purposes.
