Abstract

The invention relates to a preparation method of steroid saponin, sesquiterpenoid, phenylpropanoid glycoside and phenolic acid monomeric substances in Chinese Trillium tschonoskii Maxim. and rhizoma paridis medicinal materials and application of the monomeric substances to the preparation of medicine for treating Alzheimer disease. The monomeric substances are steroid saponin, sesquiterpenoid, phenylpropanoid glycoside and phenolic acid monomeric compounds obtained by separating, purifying and refining 30-85% ethanol elution parts of macroporous adsorption resin on the total extract of the roots and tubers, fruit or whole herb of Chinese Trillium tschonoskii Maxim. and rhizoma paridis, and the monomeric substances have biological activity on inhibiting Abeta fibril formation and stopping fibril aggregation. Due to the fact that the monomeric substances have common identical or similar mother-nucleus-structure units such as Pennogenin, Trillium tschonoskii Maxim. sapogenin, diosgenin, sterol sapogenin, furostan sapogenin and sesquiterpene aglycone, the monomeric substances have similar curative effect on the Alzheimer disease.

Description

technical field [0001] The invention relates to a preparation method of steroidal saponins, sesquiterpenoids, phenylpropanoid glycosides and phenolic acids in the roots, rhizomes or fruits of medicinal materials of the genus Trillium or Pachyphytum genus in China and their preparation methods. The application of the medicine for treating senile dementia and Alzheimer's disease belongs to the technical field of traditional Chinese medicine preparation. Background technique [0002] Alzheimer's Disease (AD) is a degenerative disease of the nervous system. The incidence rate of the elderly is high. The main clinical manifestations are memory loss, disorientation and impaired judgment and reasoning ability. Now it is more recognized that the classification of AD (that is, senile dementia) includes senile dementia, vascular dementia and mixed dementia. Senile plaques are the main pathological hallmark of AD, in which Aβ aggregation is the central link, a key factor in the pathog...
