Abstract

The vitamin E in thirty eight commercial diets for eel culture was investigated twice.
The average amounts are 5.54±1.97 mg% in 17 different kinds of diets for Futo stage (eel weighing more than 20 g) in May 1969, 8.11±2.79 mg% in 15 kinds Futo stage diets and 7.49±2.21mg% in 6 kinds younger eel diets in November 1970.
The maximum vitamin E in diets for Futo stage is four to five times higher than that of minimum.
The result of thin layer chromatography showed that the major part of vitamin E was α-tocopherol.
