Properties and stability

Use and store according to specifications, no decomposition will occur, and avoid contact with oxides

Storage method

Save in a sealed manner and place it in a ventilated and dry place to avoid contact with other oxides.

Synthesis method

It is present in a certain plant of the genus Artemisia. It can be extracted from the flower buds of Artemisia roundworm, a plant of the genus Asteraceae. Take Artemisia roundworm buds, add milk of lime (pH 11-12) and boil them in hot water. The resulting leach solution is neutralized with hydrochloric acid, then concentrated under reduced pressure, cooled, and then adjusted to pH 1-2 with hydrochloric acid. Stir and heat to obtain the cyclization solution. . The cyclization liquid is fully cooled to precipitate Shandaonian crystals. The crude product obtained is recrystallized with ethanol to obtain the finished product of Sandao Nian.


Anthelmintics. It has been used for a long time for roundworm infections with remarkable efficacy.
Synthesis of various sesquiterpenoids using chiral materials. Medical repellents.
