Two Marula, Sclerocarya birrea seed samples originating from Western Sudan, were analyzed, and the characteristics and constituents of the kernel oils were determined, including physico-chemical properties, specific gravity, oil colour, refractive index, saponification value, unsaponifiable matter, acid value, free fatty acids, and phosphorus content. Total fatty acid compostion was determined ...

A physicochemical characterization of oil from chia seeds was carried out. Proximate composition analysis showed that fat and fiber were the principal components in the raw chia flour. Physical characterization showed that chia oil has a relative density from 0.9241, a refraction index of 1.4761 and a color with more yellow than red units. Chemical characterization showed that chia oil register...

1. The effects of a dietary supplement of cholesterol on liver vitamin A stores have been determined for normal and castrated young male rats. 2. When vitamin A and cholesterol were given in the diet together, liver vitamin A stores were significantly lowered to the same degree in normal and castrated animals. No significant changes in kidney or plasma vitamin A levels were observed. 3. If the ...

CERTAIN changes in the chief chemical constituents of tissues have been studied during the metamorphosis of Lucilia sericata Meigan, commonly known as the green-bottle or sheep blow-fly by Evans (3). Since histolysis and histogenesis are very well marked in this species, it was thought advisable to extend the study to a member of a lower order in which the changes are not so drastic. A suitable...
