A novel prenylated flavanoid, isonymphaeol-D (1), together with two known compounds, isonymphaeol-B (2) and nymphaeol-B (3), were isolated from Egyptian propolis. The structures of the isolated compounds were determined by various spectroscopic methods. 1 exhibited antibacterial activity against Gram-positive (Bacillus cereus, Staphylococcus aureus) and Gram-negative strains (Serratia sp., Pseudomonos sp., Escherichia coli).
从埃及蜂胶中分离出一种新型的异戊烯基化黄酮类化合物异睡莲酚-D（1），以及两种已知化合物异睡莲酚-B（2）和睡莲酚-B（3）。通过各种光谱方法确定了分离出的化合物的结构。化合物1对革兰氏阳性菌（蜡样芽孢杆菌、金黄色葡萄球菌）和革兰氏阴性菌（沙雷氏菌属、假单胞菌属、大肠杆菌）具有抗菌活性。
