黄酮类化合物广泛存于植物界,根据不全面的统计,在最常用的750种植物药(分布于162科)中,有71科(占44%)的140种(占18.7%)含有黄酮类化合物。自1814年发现第一个黄酮类化合物白杨素(Chrysin)以来,到1973年已发现的化合物约有750种,估计到目前已有1000种化合物以上。黄酮类化合物的生物活性繁杂而多样,统计文献记载,效果比较熟知的有消炎、强心、降压、扩张冠状动脉,降低胆固醇、利尿、祛痰和护肝等活性作用。在生物活性的研究方面,早在1931年Koike首先发
Flavonoids are widely found in the plant kingdom. According to incomplete statistics, out of the 750 most commonly used botanical drugs found in 162 families, 71 (44%) and 140 (18.7%) of them contain flavonoids Compound. Since the discovery of Chrysin, the first flavonoid, in 1814, about 750 compounds have been discovered by 1973, and it is estimated that more than 1,000 compounds have been reported so far. The biological activity of flavonoids is diverse and diverse. Statistics shows that the effect of anti-inflammatory, cardiotonic, antihypertensive and coronary artery dilatation is relatively well-known. The activity of cholesterol, diuretic, expectorant and protecting liver are reduced. In bio-active research, Koike first made its debut in 1931
