Physical and Chemical Properties | Colorless orthorhombic wedge-shaped transparent crystal or white powder. Melting point 170-173 ℃, relative density 1.187. Soluble in alcohol, ether, chloroform, alkali and most volatile oil and fatty oil, slightly soluble in water. Boiling point sublimation. Shined by light, gradually yellow. At first it is tasteless, then it turns bitter and poisonous. Shan Daowan is a ketolide containing two double bonds. After dissolving in alkali, it opens the lactone ring to form a salt, which is acidified and turned back to the original. |

biological activity | Santonin (Alpha-Santonin) is the active ingredient of artemsia cina and can be used to study helminth infection. |
Use | anthelmintic. For Ascaris infection has been used for a long time, the effect is remarkable. |
production method | , it can be extracted from the flower bud of Chrysanthemum morifolium. Take the flower buds of Artemisia selengensis, add milk of lime (pH11-12), soak and cook in hot water, neutralize the obtained leaching solution with hydrochloric acid, reduce the pressure and reduce the depth, cool down, and adjust the pH to 1-2 with hydrochloric acid, after stirring and heating, a cyclization solution was obtained. The cyclization liquid was sufficiently cooled to precipitate the annual crystals of the mountain track. The obtained crude product was recrystallized with ethanol to obtain the finished product of the mountain road year.
