Five prenylated arylbenzofurans, moracins Q-U, were isolated from Morus mesozygia (Moraceae). Their structures were elucidated on the basis of spectroscopic evidence. Along with these compounds, 3beta-acetoxyurs-12-en-11-one, marsformoxide, moracin C, moracin M, moracin K, artocarpesin, cycloartocarpesin, morachalcone A were also isolated. Four of the five compounds, (moracins R-U) displayed potent antioxidant activity.
从桑科植物裂叶桑（Morus mesozygia）中分离出了五种异戊烯基化芳基苯并呋喃类化合物，即桑色素Q-U。基于光谱学证据阐明了它们的结构。除了这些化合物外，还分离出了3β-乙酰氧基乌苏-12-烯-11-酮、马桑氧化素、桑色素C、桑色素M、桑色素K、波罗蜜黄素、环波罗蜜黄素、桑查耳酮A。这五种化合物中的四种（桑色素R-U）表现出强大的抗氧化活性。
