Abstract

The invention discloses an effective part extract of valeriana amurensis P.Smirn. and a quality control method and medical use thereof. The content of total lignanoid substances in the extract accounts for over 50 percent of the total weight of the extract, wherein (+) pinoresinol-4,4'-O-beta-D-diglucopyranoside and (+) pinoresinol-8-O-beta-D-glucopyranoside are the main active components in the effective part extract, and the sum of the contents of the two active components accounts for more than 13 percent of the total weight of the extract. The invention also discloses a preparation method and the quality control method of the effective part extract. The effective part extract contains one effective part group of total lignanoid components and can effectively treat central nervous system degenerative diseases including senile dementia, tristimania and the like. The process for preparing the effective part extracts of the valeriana amurensis P.Smirn. for resisting the senile dementia can adapt to industrial production, and provides a new method for treating the central nervous system degenerative diseases by using the valeriana amurensis P.Smirn..

Description

technical field [0001] The present invention relates to extracts from effective parts of Chinese herbal medicines, in particular to extracts from effective parts of Valeriana amurensis Smir. The use of part extracts in treating degenerative diseases of the central nervous system belongs to the field of effective part extracts of the genus Valeriana. Background technique [0002] Blackwater valerian is the dry root and rhizome of Valeriana amurensis Smir. Blackwater valerian is mainly distributed in Northeast China, and is rich in resources in the Greater Khingan Mountains. Plants of the same genus have been used to treat various diseases such as insomnia, and also have different pharmacological effects on the nervous system, cardiovascular and cerebrovascular, and anti-tumor. The latest research has found that the chemical components of Valeriana have beneficial effects on the neurodegenerative disease senile dementia. Therapeutic effect. But so far there is no relevant r...
