Phylloquinone (vitamin K1) content of vegetables
Assessment of vitamin K (VK) dietary intakes has been limited by incomplete VK food composition data for the US food supply. The phylloquinone (VK-1 or vitamin K1) concentrations of a variety of geographically representative vegetables (n 1⁄4 218) were determined by reversed-phase high performance liquid chromatography with fluorescent detection. Green leafy and flower vegetables including broc...

Vitamin K1 intestinal absorption in vivo: influence of luminal contents on transport.
Intestinal absorption of [3H]phylloquinone was investigated in the unanesthetized rat by the use of a technique of recirculating perfused isolated intestinal segments. Apparent saturation kinetics were found as the concentration of the vitamin in the perfusate was increased in a stepwise fashion from 15 nM to 300 muM. Alkalinization of the perfusate or the addition of 2.5 mM linoleic acid to th...
