Abstract
The authors could prepare the concentrated kitol by comparatively easy method, containing a trace of vitamin A, as material for further studies on kitol. Unsaponifiable matters, prepared from fin whale liver oil by usual method, were dissolved in petroleum ether and then a part of unsaponifiable matters was extracted repeatedly with 90% methanol from the petroleum ether solution. The extracted and remained substance were examined by means of the spectrum analysis and Carr-Price reaction. It has been confirmed that the methanol extract was vitamin A and the remains in petroleum ether was kitol.
