黄酮类化合物在许多品种的植物中自然存在,它们是许多药物和食品添加剂的原料,如日本的一种调味品“Sumac”对鼠伤寒沙门氏菌TA_(98)菌株是致突变的,它的作用成份已查明为一种黄酮—檞皮酮。黄酮类化合物作为主要的环境污染物,已逐渐引起重视。一些学者用Ames试验对植物黄酮类进行了大规摸的致突性研究,结果引起TA_(98)菌株的突变 Flavonoids naturally exist in many varieties of plants, and they are the raw materials for many drugs and food additives. For example, a Japanese spice “Sumac” is mutagenic to S. typhimurium strain TA_98, and its active ingredient It has been identified as a flavonoid, quercetin. As a major environmental pollutant, flavonoids have gradually attracted attention. Some scholars used the Ames test to conduct large-scale and sudden morphological studies on plant flavonoids, resulting in mutations in the strain TA_98.
