Vinpocetine is a semi-synthetic derivative of vincamine, an alkaloid derived from Vinca minor L. that has been used since the 1970s in Japan, Europe, Mexico and Russia for the treatment of cognitive and cerebrovascular disorders.
Vinpocetine may also be derived from tabersonine, an alkaloid extracted from the seeds of African Voacanga.
Covex S.A. is a global manufacturer of Vinpocetine, our facilities located in Europe (Spain), make our Vinpocetine meet the highest standards. Using a proprietary patent (ES 549.105) to obtain vinpocetine through tabersonine, an alkaloid extracted from the African Voacanga.
Vincamine (VC) is also an alkaloid of the eburnamenine type.
