The authors presented papers on a physicochemical determination of vitamin D in fish and fish products in 1964. This paper reviews the recent developments of the methods to determine vitamin D in natural products. Since about 1960,there have been put some important improvements on the treatment of samples and the application of thin layer and gas liquid chromatography, gel filtration, mass spectrography etc. However, many of difficulties existing in the method of that time were not yet solved, especially in the case of vitamin D determination of natural products such as meats, dairy products, animal tissues or excrements. Further improvements are needed especially in the separation of vitamin D from large amounts of impurities such as sterols or vitamin A, and simplification of complicated procedures adopted in various methods of determinations.
