Properties and stability

1. Exists in flue-cured tobacco leaves and burley tobacco leaves.

2. It is unstable and decomposes under the action of light, oxidants, strong acids or halogens. Participates in the synthesis of prothrombin in the liver.

Storage method

This product should be sealed and stored in a cool, dry place.

Synthesis method

1. Obtained from toluoquinone reduction, acetylation, condensation with phytol, etc., and then oxidation. It can also be extracted from alfalfa or other plants.

2.O-menaquinone and acetic anhydride are reduced and acetylated in the presence of zinc to form acetylated menaquinone, which is hydrolyzed and condensed Dihydrogenated vitamin K1 is obtained, which is then hydrolyzed,oxidized, purified, and refined.

3. Tobacco: FC, BU, 1.

Purpose

1. Mainly used to treat neonatal malabsorption or vitamin deficiency caused by drugs and hypoprothrombinemia caused by broad bean anticoagulant drugs.

2.It is used as a food fortifier and can be used in infant food. The dosage is 420~475μg/kg.
