Product Introduction

Vinpocetine is a semisynthetic derivative of the alkaloid vincamine, an extract from the periwinkle plant.Vinpocetine is reported to have cerebral blood-flow enhancing and neuroprotective effects, and is usedas a drug in Eastern Europe for the treatment of cerebrovascular disorders and age-related memoryimpairment.It binds tubulin, thereby inhibiting the assembly of microtubules. It is M phase cell cycle specific since microtubules are a component of the mitotic spindle and the kinetochore which are necessary for the separation of chromosomes during anaphase of mitosis. Toxicities include bone marrow suppression (which is dose-limiting), gastrointestinal toxicity, potent vesicant (blister-forming) activity, and extravasation injury (forms deep ulcers).Vinblastine paracrystals may be composed of tightly-packed unpolymerized tubulin or microtubules.


Vinpocetine is a kind of drug for improving cerebral vessels, which has the effect of expanding cerebral vessels, improving cerebral metabolism and improving cognition.
1, expansion of cerebral vessels long spring etine can expand cerebral vessels, increase blood flow to the brain, for cerebral thrombosis, cerebral infarction and other diseases have a certain therapeutic effect, but also can prevent the recurrence of cerebral infarction.
2, improve brain metabolism vinpocetine can improve brain metabolism, promote the repair and regeneration of nerve cells, for brain nerve function damage, memory loss, senile dementia and other diseases, has a certain therapeutic effect.
3, improve cognition Vinpocetine can improve cognition, improve cognitive ability, chronic brain ischemia, cerebral blood insufficiency, mild cognitive dysfunction, etc., has a certain therapeutic effect.
In addition, vinpocetine also has the effect and efficacy of inhibiting platelet aggregation. Patients need to use drugs correctly under the guidance of doctors, and can not blindly use drugs, so as not to aggravate the condition and not conducive to the recovery of the body. If discomfort occurs during the use of drugs, it is necessary to stop the drug and seek medical treatment in time.

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.

1.Applied in the food field, it has become a new raw material which used in food and beverage industry;
2.Applied in the health product field;
