Production methods

1. Reduction, acetylation, condensation with chlorophyll and oxidation of toluene quinone. It can also be extracted from alfalfa or other plants.

2. Methyl naphthoquinone is reduced and acetylated into acetylated menaphthoquinone in the presence of zinc by o-methylnaphthoquinone and acetic anhydride. After hydrolysis and condensation, dihydrogenated vitamin K1 is obtained, which is then hydrolyzed, oxidized, purified and refined.

3. Tobacco: FC,BU,1. [1]
