Identification of d- or di-∝-Tocopherol in Pharmaceuticals, Food Supplements, or Feed Supplements: A Collaborative Study
Autor: Emma-Jane E Drury, Stanley R. Ames
Publikováno v: Journal of AOAC INTERNATIONAL. 58:585-594
A collaborative study was conducted to evaluate a method for identifying d- or dl-∝-tocopherol in pharmaceuticals, food supplements, or feed supplements. The sample is extracted and saponified, the extraneous color is removed by chromatography, and

Age, parity, and vitamin A supplementation and the vitamin E requirement of female rats1,2,3
Autor: Stanley R. Ames
Publikováno v: The American Journal of Clinical Nutrition. 27:1017-1025
The objective was to determine the amount of d.a-tocopheryl acetate needed for successful reproduction in rats at various ages, of different parities, and at several levels of vtiamin A supplementation. The median fertility dose was determined by usi

Autor: D. R. Nelan, Stanley R. Ames, F. H. Tinkler, F. V. Passero
Publikováno v: Journal of AOAC INTERNATIONAL. 49:1060-1066
A procedure has been developed to distinguish between supplemental d- and dl-atocopheryl acetate in premixes, feed concentrates, and feeds. Tocopheryl acetate in a crude extract is partially purified by oxidative adsorption, de-esterified by saponifi

Methods for Evaluating Vitamin A Isomers
Autor: Stanley R. Ames
Publikováno v: Journal of AOAC INTERNATIONAL. 49:1071-1078
Precise estimation of the biological activity of the vitamin A in various products is complicated if cis isomers are present because they have lower biopotencies than alltrans isomer. Two general types of vitamin A sources contain cis isomers; the tr
