Abstract

The invention provides a spiraea salicifolia stem and branch anti-rheumatoid-arthritis effective part and a preparation method and application thereof.According to the effective part, spiraea salicifolia stems and branches serve as raw materials, extract is obtained after 60% ethyl alcohol reflux extraction and ethyl alcohol pressure reduction recovery, the extract is purified with macroporous adsorption resin, and the total lignanoside effective part is obtained.The sum of weights of (+)-8'-hydroxy pinoresinol-8'-O-beta-d-glucopyranoside, (7R,8S)-dihydro dehydrogenation bis-coniferyl alcohol-9'-O-beta-d-glucopyranoside, (+)-lyonia ovalifolia tree ring lignans-9-O-beta-d-glucopyranoside and (+)-isolariciresinol-9-O-beta-d-pyran xyloside in the effective part ranges from 40% to 50%.The effective part is determined through the method that a modern separation means and pharmacological activity screening are combined, the ingredients of obtained effective part are clear, the content of active ingredients is high, it is shown through the in-vitro and in-vivo experiment results that the spiraea salicifolia stem and branch anti-rheumatoid-arthritis effective part inhibits generation of pro-inflammatory cytokine tumor necrosis factor-alpha, interleukin-1 beta and interleukin-6 to achieve the effect of treating rheumatoid arthritis.

Description

technical field [0001] The invention belongs to the field of medicine, and relates to the anti-rheumatoid arthritis effective parts of Spiraea lanceolata stems and a preparation method thereof, and also relates to the anti-rheumatoid arthritis effective parts of Spiraea willow stems and branches in the preparation and treatment of rheumatoid arthritis. Uses in Arthritis Products. Background technique [0002] Rheumatoid arthritis is a common autoimmune disease characterized by chronic inflammatory lesions of joint tissues. The main pathological changes are the infiltration of synovial cells, the formation of synovial pannus, and the erosion of cartilage and bone tissue. The goal of rheumatoid arthritis treatment is to arrest the progression of the disease, that is, to stop the process of joint inflammation and destruction, and to prevent loss of function. Although there are many treatment measures, drug treatment is still the basis. Current treatments include non-steroida...
