Abstract

The invention discloses application of pepper plant essential oil, namely application of pepper plant essential oil in the preparation of drugs or health products for treating and preventing Alzheimer's disease; the application of the pepper plant essential oil in the preparation of drugs or health products for treating and preventing Alzheimer's disease is attributed to the action mechanism of the pepper plant essential oil in significantly inhibiting acetylcholinesterase activity, and in-vivo activity experiment further verifies that the pepper plant essential oil can significantly improve Alzheimer's disease and its symptoms, and the application is totally different from that of existing drugs or health products of pepper plant essential oil.

Description

technical field [0001] The invention relates to a new application of the essential oil of plants of the genus Piper, in particular to the application of the essential oil of the genus Piper in preparing medicines and health products for treating and preventing Alzheimer's disease. Background technique [0002] Alzheimer's disease (AD), also known as senile dementia, is a neurodegenerative disease with insidious onset and progressive development. Clinically, it is characterized by comprehensive dementia such as memory impairment, aphasia, apraxia, agnosia, impairment of visuospatial skills, executive dysfunction, personality and behavior changes, and severe negative social, occupational and life functions. The etiology of AD is still unknown. In recent years, many researchers at home and abroad have proposed various pathogenic hypotheses from different angles, such as hypocholinergic hypofunction hypothesis, inflammation and immunity hypothesis, gene mutation hypothesis, amyl...
