biological activity
Digitoxin is an effective Na +/K +-ATPase inhibitor with an EC50 value of 0.78 μM.
Production method
In nature, the active ingredients of digitalis leaves and other cardiotonic drugs are steroidal glycosides, and the secretions of toads in animals also contain similar substances. In the digitalis glycoside molecule, sugar binds to the hydroxyl group of C3. Glycosides have a butene lactone structure. In the pharmaceutical industry, digitalis leaf powder is added with water to make alcohol at 28-35 ℃, fermented leaf powder is extracted with 70% ethanol, concentrated and filtered. The concentrated solution was removed at 28-30 ℃ for 4-6h, and then extracted with chloroform. The extract is washed with water, 5% sodium hydroxide solution and water in turn, concentrated to viscous form, added with anhydrous acetone crystal, placed overnight at 0-5 ℃, and filtered to obtain wet product. After column chromatography purification and digitoxin.
