Phylloquinone is a polycyclic aromaticketone, based on 1,4-naphthoquinone, with 2-methyl and 3-phytyl functional groups. In science, a common name is any name by which a species or other concept is known that is not the official scientific name. ...

Phylloquinone refers to a branch of Vitamin K which is a fat-soluble vitamin required for the normal clotting of the blood.
Vitamin K is found in two forms in nature: Phylloquinone or Vitamin K1 which is found in plants and Menaquinone or Vitamin K2 which can be synthesized by many bacteria.
Phylloquinone is present in a number of dietary sources that includes: green leafy vegetables such as spinach; green tea; cabbage; turnip greens; brussels sprouts; alfafa; eggs; soybean oil; canola oil; olive oil; soybeans; cheddar cheese; oats; cauliflower; asparagus; coffee; cow milk; and bacon.
To determine the influence of vitamin E on phylloquinone activity, one day-old chicks were raised on a masch diet supplemented with different amounts of vitamin E for 31 days.
In chicks fed a diet high in vitamin E (4000 mg allrac-alpha-tocopheryl acetate/kg) but adequate in vitamin K (0.14 mg phylloquinone/kg) a threefold increase in prothrombin time and an increase in mortality rate (five out of twelve animals died from increased bleeding tendency) was observed.
Plasma and liver alpha-tocopherol levels correlated with dietary amounts of vitamin E. Increased phylloquinone levels in the diet did not significantly influence alpha-tocopherol concentrations in plasma and liver, but coagulopathy caused by high vitamin E intake could be reversed.
