Outline of Final Research Achievements

This study investigated the usefulness of the high-performance liquid chromatography method as the measurement of vitamin K in human milk for the purpose of increasing vitamin K concentration in human milk of lactating woman ate vitamin K rich food, Natto. As vitamin K concentration in human milk, Menaquinone-4 (MK-４) was 1.9±1.0ng/mL and Phylloquinone (PK) was 2.8±1.0ng/mL. These results agree with the previous reports. This study showed that the HPLC method was useful as a measurement of the vitamin K in breast milk.
