BACKGROUND New high-performance liquid chromatography (HPLC) method was developed for the determination of vitamin K1 and two forms of vitamin K2 (MK-4 and MK-7) in human serum, and the levels of vitamin K were determined in 350 samples of postmenopausal women. METHODS Vitamin K was determined by HPLC with fluorescence detection after postcolumn zinc… CONTINUE READING
