The invention relates to a preparation method of the total flavone in the leaf of yellow berry and the application in the preparation of the protective blood vessel medicine. After the drying of the dried yellow berry leaves, the 7h is soaked in the 55% alcohol 65% ethanol, and the ultrasonic treatment is carried out, and then the soaking solution is filtered out. Then the percolation was carried out with the volume of 8 times the volume of 55% and 65% ethanol, and the soaking solution and percolate were reduced to no alcohol, and the concentration of water diluted solution was 0.25g/ml. Add ethyl acetate to extract 3 times, and combine the extract to dry dry cream. The dry paste was dissolved in water and diluted to 15 25mg/ml by elution of AB ethanol 8 macroporous adsorption resin column with 55% ethanol. The yield of flavonoids extracted from Chinese wolfberry leaves was more than 20%. This method can improve the extraction rate, shorten the extraction time, reduce the concentration of ethanol used in percolation, and the total flavonoids in the leaves of yellow berry leaves have the effect of protecting blood vessels, and the application of total flavonoids of yellow berry in the preparation of protective blood vessel drugs is realized.

一种黄杞叶总黄酮的制备方法及其在制备保护血管药物中的应用
本专利技术涉及医药,特别是一种黄杞叶总黄酮的制备方法及其在制备保护血管药物中的应用。
技术介绍
糖尿病是一种慢性代谢障碍性疾病,其患病率、致残率和病死率在慢性病中居第三位。我国患者人数已居全球首位。截止2011年初,我国18岁及以上人群群体样本中,估测糖尿病发病率为11.6%,约有1.139亿患者。预计到2030年,全球糖尿病患者人数将增加至5.52亿人。糖尿病又分为1型和2型,其中2型糖尿病(T2DM)的发病机制主要体现在胰岛素抵抗及胰岛素分泌缺陷。目前,2型糖尿病慢性血管并发症的心血管风险极大,70-80%糖尿病患者主要死亡原因不是糖尿病本身,而是动脉粥样硬化性心血管疾病(ASCVD)并发症,如冠心病、缺血性脑卒中及外周动脉疾病等。目前,国内外糖尿病防治指南均推荐,对于T2DM患者,必须加强高血糖、高血压、血脂异常、肥胖等多重心血管危险因素的综合管理,以最大限度降低心血管事件和死亡风险。因此,对于合并ASCVD的T2DM患者而言,除了降糖治疗,还应辅以降脂、降压等治疗,对这类患者进行全面综合管理。目前临 ...
