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.
