[0012] CN1311002A (00102073.0, Shi Lixia) discloses a refined bear bile powder and a preparation method thereof, which belongs to the field of pharmacy. Common bear bile powder is easy to absorb moisture and agglomerate, has a sticky tooth feeling, extremely fishy smell, extremely bitter taste, many impurities, and slow absorption. The property is unstable and easy to be corrupted, and the content of active ingredients is low, which limits the application range of bear bile powder. Oral application often adds flavoring agents to reduce the stench

Embodiment 1

[0081] Embodiment 1: prepare refined bear bile powder

[0082] (1) the bear bile collected (without tube drainage method) (when it is dried under reduced pressure to obtain powder, measure the content of tauroursodeoxycholic acid and taurochenodeoxycholic acid in this powder, be respectively 22.63% And 16.31%, this data is the percentage content of two kinds of materials in bear bile solids) add water dilution (add 2.5 times of volume water dilutions), filter with 80 mesh screens, 80 mesh screens are filtered gained filtrate and use 1M hydrochloric acid Solution adjusts its pH=3.3, then adds 1.2% sodium chloride in the filtrate, obtains crude bear bile fluid (this crude bear bile fluid is dried under reduced pressure to obtain powder, measure tauroursodeoxycholic acid and taurine angiosperm in this powder The content of deoxycholic acid is 28.47% and 20.33% respectively, which shows that the ratio of the two is basically unchanged before filtration, but it is concentrated du...

Embodiment 2

[0102] Embodiment 2: prepare refined bear bile powder

[0103] Steps (1) to (4) are carried out according to Example 1; in step (5), the ethyl acetate-ether (5:1) mixture used is changed to ethyl acetate, and the precipitate is dried under reduced pressure to remove the solvent to obtain refined Bear bile powder. It was determined that the melting point of the refined bear bile powder was 162-163° C., and the difference in melting point indicated that it had a different crystal form from the refined bear bile powder in Example 1.

Embodiment 3

[0104] Embodiment 3: prepare refined bear bile powder

[0105] Steps (1) to (4) are carried out according to Example 1; in the step (5), the ethyl acetate-ether (5:1) mixed solution used is changed to ether, and the precipitate is dried under reduced pressure to remove the solvent to obtain refined bear bile pink. It was determined that the melting point of the refined bear bile powder was 173-175° C., and the difference in melting point indicated that it had a different crystal form from the refined bear bile powder in Example 1.

[0106] The above results of Example 2 and Example 3 show that in step (5) the mixture of ethyl acetate-ether (5:1) can be used to obtain the T crystal form with a melting point of 187-189°C, instead of using this mixture The crystals obtained are different.

[0107]Place 3 months at 45 ℃ of temperature places to embodiment 1~3 gained three kinds of refined bear bile powders, then measure their fusing points, the fusing points of three batches o...

Abstract

The invention relates to refined bear gall powder for reducing blood fat and preventing and treating heart cerebrovascular disease and atherosclerosis, in particular to an application of a compound represented as the formula I in preparation of products for reducing blood fat and cholesterol, preventing and / or treating the heart cerebrovascular disease and preventing and / or treating the atherosclerosis. The compound adopts Cu-Kalpha radiation and has diffraction peaks at angles of 8.53 + / - 0.20 degrees, 10.96 + / - 0.20 degrees, 12.03 + / - 0.20 degrees, 13.14 + / - 0.20 degrees, 14.82 + / - 0.20 degrees, 17.26 + / - 0.20 degrees, 22.53 + / - 0.20 degrees, 24.21 + / - 0.20 degrees, 26.68 + / - 0.20 degrees, 29.42 + / - 0.20 degrees and 31.24 + / - 0.20 degrees in a powder X-ray diffraction pattern representedby the 2-theta angle. The compound shows excellent biological performance such as excellent bioavailability and can play physiological activity the same as that of bear gall powder or tauroursodeoxycholic acid. For instance, the refined bear gall powder can be used for reducing blood fat and cholesterol, preventing and / or treating the heart cerebrovascular disease and preventing and / or treating the atherosclerosis.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to a bear bile powder product and a preparation method thereof. The bear bile powder product exhibits excellent biological effects, for example, it can be used to lower blood lipids or further lower cholesterol to prevent and / or treat cardiovascular and cerebrovascular diseases and atherosclerosis. Background technique [0002] Bear bile has been used as medicine for more than 1,000 years. It is known as the "gold in medicine" and ranks first among the four major animal medicinal materials: bear bile, tiger bone, bezoar, and musk. At present, there are 153 kinds of Chinese patent medicines made from bear bile powder alone and compound Chinese patent medicine preparations containing bear bile powder, involving 183 drug manufacturers. Its comprehensive effects cannot be replaced by other drugs. Among the 660 classics of traditional Chinese medicine (including more than 80,000 traditi...
