Analyses of Drugs and Chemicals by Infrared Absoption Spectroscopy I. Determination fo dl-alpha-Tocopherol and Its Acetate in Pharmaceutical Preparation

적외선 흡수 스펙트람에 의한 의학품 분석연구 I dl-alpha-Tocopherol 및 dl-$\alpha$-Tocopherol Acetate의 정량분석

Determination of dl${\alpha}$-tocopherol and its acetate in their preparation through Infrared absorption spectrum was examined, using the sharp bands at 1085cm$^{-1}$ and 1210cm$^{-1}$ res[ectovely as the key bands. The accuracy of the determination was 100${\pm}$2% to the weight taken.
