Embodiment 1

[0021] Example 1: Compound (I) Separation Preparation and Structure Confirmation

[0022] Separation method: (a) Grind the dry rhizome (2kg) of Anemarrhena anemarrhena, extract with 80% ethanol under heat reflux (15L×3 times), combine the extracts, concentrate until no alcohol smell (3L), and then use petroleum ether (3L ×3 times), ethyl acetate (3L×3 times) and water-saturated n-butanol (3L×3 times) were extracted to obtain petroleum ether extract, ethyl acetate extract and n-butanol extract respectively; (b) In step (a), the ethyl acetate extract was removed with D101 type macroporous resin, first eluted with 25% ethanol for 8 column volumes, then with 70% ethanol for 12 column volumes, and collected 70% eluate, Concentrate under reduced pressure to obtain a 70% ethanol elution concentrate; (c) in step (b), the 70% ethanol elution concentrate is separated with normal phase silica gel, and the volume ratio is 85:1 (10 column volumes), 45: The dichloromethane-methanol gradien...

Abstract

The invention discloses a pharmaceutical composition of buspirone hydrochloride and its medical application. The pharmaceutical composition of buspirone hydrochloride provided by the invention contains buspirone hydrochloride and a kind of dried rhizome of Anemarrhena anemarrhena The isolated natural product compound (I) with a novel structure, when buspirone hydrochloride and the compound (I) provided by the present invention act in combination, can make the synoviocytes stagnate in the G1 phase of the cell cycle, thereby inhibiting the proliferation of the synoviocytes, Treating synovitis; the therapeutic effect is better than that of buspirone hydrochloride or compound (I) alone. The composition of buspirone hydrochloride and compound (I) can be developed into a drug for treating synovitis, which has outstanding substantive features and significant progress compared with the prior art.

Description

technical field [0001] The invention belongs to the field of biomedicine and relates to a new application of buspirone hydrochloride, in particular to a pharmaceutical composition of buspirone hydrochloride and its medical application. Background technique [0002] Buspirone Hydrochloride Tablets is a new anti-anxiety drug, which mainly changes anxiety by activating serotonin (5-HT) 1A receptors in the brain. [0003] Knee synovitis is a sterile form of inflammation that results from knee sprains and various intra-articular injuries. Abnormal function of the synovial membrane can cause the joint fluid to not be produced and absorbed normally, and effusion will occur in the knee joint. The morphological change of the synovial membrane will also invade the cartilage of the knee joint. If it is not treated in time, it will lead to osteoarthritis of the knee joint, and there is a great risk of disability. [0004] So far, there is no report on the correlation between buspirone...
