Description

technical field

[0001] The present invention relates to a method for extracting galantamine from raw materials of Lycoris or Galanthus, in particular to a method for extracting galantamine from raw materials of Lycoris or Galanthus by applying supercritical fluid extraction technology (supercritical fluid extraction, hereinafter referred to as SCFE). A new method of extracting galantamine. Background technique

[0002] Galantamine is a tetracyclic alkaloid, which is a cholinesterase inhibitor with reversible action due to its pharmacological properties. It can easily pass through the blood-brain barrier and produce strong central effects. Alzheimer's dementia (also known as Alzheimer's disease, Alzheimer'sdisease, AD) is a common senile neurodegenerative disease, and it is currently the third most expensive medical cost in the United States after heart disease and cancer. more than one disease. Galantamine, as a specific, competitive, and reve...
