The antisterility activity of
-tocohydroquinone in vitamin E-deficient female rats has been re-examined.
For this purpose, the hydroquinone was prepared daily by the catalytic hydrogenation of
-tocoquinone which was free of
-tocopherol.
When injected at a level of 5 mg daily, the
-tocohydroquinone exhibited antisterility activity. Smaller doses cured the muscle lesions in the mother but did not prevent fetal death and resorption.
