Abstract
Novel process for biochemical optical resolution of 2DL-racemic compound of .alpha.-tocopherol ester or substances which contain the same, using culture broth, whole cell, or culture filtrate, which are obtained by cultivating microorganisms which possess an ability for hydrolysis of said ester. Beneficial advantage of the process resides in its low cost, simplicity and high resolution ratio.
