• When the benzene solution of vitamin K1 was irradiated with ultraviolet light many colored and fluorescent degradation products were produced as detected in thin layer chromatography according to the following scheme.The spot 2 substance is the compound produced by the change of the phytyl double bond but the latter bond is not required for the formation of the spot 3 and 4 substances. The spot 3 substance is identified as phthiocol and is one of the final degradation products.
