biological activity | Convallatoxin are cardiac glycosides isolated from Adonis amurensis Regel et Radde. Convallatoxin improved colitis by activating PPARγ and inhibiting NF-κB. Convallatoxin is a P-glycoprotein (P-gp) substrate and recognizes Val982 as an important amino acid involved in its transport. Convallatoxin is an enhancer of ligand-induced MOR endocytosis, with high potency and efficacy. It has anti-inflammatory and anti-proliferative properties. |

chemical properties | white crystalline powder. Melting point 235-242 ℃. Soluble in alcohol and acetone, slightly soluble in water and chloroform, almost insoluble in ether and petroleum ether. |
use | cardiotonic drugs. Similar to digitalis preparation. Mainly used for acute and chronic heart failure. |
production method | the coarse powder of the overground part of lily of the valley (regalia) is extracted with benzene-ethanol mixed solvent. after the extraction solution is concentrated, the chloroform-ethanol solution is used to extract the concentrated solution, and the extracted solution is also concentrated. this time, the concentrated solution is extracted with water. The obtained aqueous solution is concentrated and cooled to crystallize out the crude pantoin of lily of the valley. The crude product is recrystallized with methanol to obtain the finished product. The total yield is 0.01% for the whole plant of lily of the valley. |
