Abstract

The invention discloses application of lutein in preparation of medicaments for preventing and treating cerebral vascular diseases. The lutein can be extracted by using a plurality of methods, is wide in source and high in safety. Pharmacodynamic studies show that the lutein can be applied to preventing and treating cerebral ischemia, cerebral hemorrhage, cerebral anoxia and vascular dementia, and other cerebral vascular diseases.

Description

technical field [0001] The invention relates to a new medical application of lutein, in particular to the application of lutein in drugs for preventing or treating cerebrovascular diseases, and belongs to the technical field of medicine. Background technique [0002] Cerebrovascular disease is one of the three major causes of death and the first cause of disability in adults, and it is also one of the important causes of senile dementia and psychological disorders. With the progress of society, the improvement of living standards and the aging population, the onset of cerebrovascular diseases is becoming younger and younger. There are about 2 million new patients in the country every year, and about 1.5 million patients die of cerebrovascular diseases, which seriously threatens human health and life safety. . Therefore, it is of great significance to develop drugs for the prevention and treatment of cerebrovascular diseases. [0003] Lutein, also known as lutein, is an oxy...
