Zusammenfassung:	PURPOSE:To obtain the subject new derivative useful as an antioxidant by separating the derivative from Saccharomyces cerevisiae useful as baker's yeast. CONSTITUTION:Dried cells of Saccharomyces cerevisiae as baker's yeast are ground by a ball mill, extracted with a mixed solution of chloroform and methanol and a fraction is collected by a column packed with silica gel 60 to give the objective derivative of the formula (R1 is H or acyl; R2 is alkyl).
