槲皮素(Quercetin)化学名为3,5,7,3＇,4＇-五羟基黄酮,属黄酮类(Flavon-oid)化合物,在植物中多以甙的形式存在,一般存在于某些植物的花、叶、果实部分。如芦丁(芸香甙)、槲皮甙、金丝桃甙等,经酸水解可得到槲皮素。从本世纪初直到最近,约八十年间,国内外学者对槲皮素的提取、纯制、结构测定、理化性质、合成衍生物、药理与临床都进行了大量的研究工作。据报道槲皮素具有祛痰、止咳、平喘、强心、降血压、扩张冠脉、降血脂、抗炎、抗过敏、解痉、抗癌等广泛的药理作用。最近报道,槲皮素还具有抗出血作用。七十年代初以来,国内在结合慢性气管炎的防治中,江西、湖南、吉林等地将槲皮素制成片
Quercetin has a chemical name of 3,5,7,3’,4’-pentahydroxyflavone and is a Flavonoid compound. It is found in plants in the form of terpenes and is generally found in certain species. The flower, leaf, and fruit parts of the plant. Such as rutin (Ruta citrifolia), quercus tincture, hypericum tincture, etc., can be obtained by acid hydrolysis quercetin. From the beginning of this century until recently, about 80 years ago, domestic and foreign scholars have conducted a lot of research work on the extraction, purification, structure determination, physicochemical properties, synthetic derivatives, pharmacology, and clinical aspects of quercetin. Quercetin has been reported to have a wide range of pharmacological effects such as expectorant, cough, asthma, cardiac, blood pressure, coronary artery, blood fat, anti-inflammatory, anti-allergic, antispasmodic, anticancer and so on. Recently reported that quercetin also has anti-bleeding effect. Since the early 1970s, in the prevention and control of chronic bronchitis in China, quercetin has been made into tablets in Jiangxi, Hunan and Jilin.
