The optimum conditions for the determination of vitamin K3 (VK3) in the plasma by differential pulse polarography were examined. This technique, after ether extraction, was found to be useful for the determination down to a level of 3×10-7M of VK8. The recovery of VK8 added to the plasma (4.0×10-6M) was more than 90%. At this concentration the coefficient of variation (n=4) was 5.5%.
