抄録

Vitamin K_1 (K_1) and vitamin K_2 (MK-n) in foods were measured by a method based on high-performance liquid chromatography (HPLC) combined with chemical reduction and fluorometric detection. The vitamins extracted from foods were purified with a silica SEP-PAK cartridge and/or thin-layer chromatography (TLC) and a silica SEP-PAK cartridge followed by TLC, respectively, and then measured by using an HPLC system. More than 1μg/g or ml of K_1 was found in salad oil, spinach leaf, green welsh onion, broccoli, purple laver, hijiki, wakame, green tea and black tea, and MK-n was mainly found in fermented foods.
