DL-a-Tocopheryl Acetate, 421,

Figure 10.9 shows the chromatograms of fortified coconut oil obtained by using (a) normal-phase HPLC and (b) GPC/normal-phase HPLC. As can be seen from these figures, chemical interferences due to lipid material in the oil were eliminated by using the MD system that was used for quantitative analysis of all of the compounds, except DL-a-tocopheryl acetate, where the latter was co-eluted with a trigliceride compound and needed further separation.

Vitamin E acetate (DL-a-tocopheryl acetate) [7695-91-2] M 472.8, m -27.5 , b 194-196 /0.01mm, 222-224 /0.3mm, d 0.958, n o 1-4958. It is a viscous liquid which is purified by distn under high vacuum in an inert atm and stored in sealed ampoules in the dark. It is considerably more stable to light and air than the parent unacetylated vitamin. It is insoluble in H2O but freely soluble in organic solvents. All eight stereoisomers have been synthesised. The commercially pure d-a-tocopheryl acetate (2R,4 R,8 R) has b 180-200°/0.7mm and [a] +3.9° (c 5, EtOH). [Cohen et al. Helv Chim Acta 64 1158 7987.]... [Pg.576]

Note The international unit of vitamin E is equal to one mg of standard eff-o-tocopheryl acetate. The d-form is more active 1 mg = 1.36 I, U. J- -Tocopheryl acetate has 42% of rhe activity of d-o- -rocopheryl acetate in the rat hemolysis test. Based on this activity a potency ratio of 1.4 1.0 for d-a-tocophery] acerate compared to dl-a-tocopheryl acetate has been established. [Pg.1580]

The d-form of the vitamin is the most active. Any studies of vitamin supplementation, and their subsequent effects in various muscle foods, must acknowledge the form of tocopherol fed before conclusions can be drawn regarding dietary uptake and antioxidant efficiency, d-a-tocopherol or its ester is more readily assimilated into tissues than the racemic (dl) form (Hidiroglou et al., 1988). Burton et al. (1988) have demonstrated that the uptake of the free phenol and acetate forms of d-a-tocopherol are equivalent. Marusich et al. (1975) reported that dl-a-tocopherol and dl-a-tocopheryl acetate were equivalent in terms of uptake by chicken liver and breast muscle, and resulted in similar oxidative stabilities within the tissue types.
