Vinpocetine is a semisynthetic derivative alkaloid of vincamine, and also can be semisynthesized from tabersonine, an extract from Voacanga Africana Seed.
Clinical studies suggest that it facilitates cerebral metabolism by improving cerebral blood flow, increasing glucose and oxygen utilization by neurons and concentration of neurotransmitters involved in the process of memory formation.
Production Function of Extract Vinpocetine
1) Vinpocetine is chemically related to, and derived from vincamine, an alkaloid found in the periwinkle plant.
2) It was introduced into clinical practice in Europe more than two decades ago for its role in cerebrovascular
disorders and related symptoms.
3) Experiments with this periwinkle extract indicate that it can dilate blood vessels, cross the blood-brain
barrier, enhance circulation in the brain, improve oxygen utilization, make red blood cells more pliable, and
inhibit aggregation of platelets.
4) Vinpocetine even has antioxidant properties. Levels peak in the bloodstream within an hour and a half
after ingestion.
