Abstract A further investigation of the isoflavonoid constituents in an extract of Piscidia erythrina root bark has yielded 23 compounds, including 18 new 5,7-dihydroxylated isoflavones, and two new coumaronochromones related to lisetin. The extracts additionally contained three 5-deoxyisoflavones, only one of which has previously been reported. All the 5,7-dihydroxyisoflavones, and both the coumaronochromones
摘要 进一步研究了红皮鱼根皮提取物中的异黄酮成分,得到了 23 种化合物,包括 18 种新的 5,7-二羟基异黄酮和两种与李司汀相关的新香豆素色酮。提取物还含有三种 5-脱氧异黄酮,此前仅报道过其中一种。所有的 5,7-二羟基异黄酮和香豆素色酮都具有含有醇羟基的五碳侧结构。简要讨论了 Piscidia 异黄酮之间可能的生物遗传关系。
