包括E.sacleuxii在内的刺桐属植物传统用于治疗微生物感染和疟疾。黄酮类和异黄酮类化合物是其活性成分。作者以抗疟活性为导向,从E.sacleuxii中分得1新的异黄酮类成分——7-羟基-4′-甲氧基-3′-异戊烯基异黄酮(1)(俗称:5-去氧-3′-异戊烯基鸡豆黄素A)及其他黄酮类,并测定了它 Erythrina plants, including E. sacleuxii, are traditionally used to treat microbial infections and malaria. Flavonoids and isoflavones are active ingredients. The authors took anti-malarial activity as the guide, and obtained a new isoflavone component from E. sacleuxii, 7-hydroxy-4’-methoxy-3’-prenyl isoflavone (1) (commonly known as: 5-deoxy-3’-prenyl chickpea A) and other flavonoids, and assayed it
