(+)-oleuropeic acid derivatives, eucalmaidins A−E (1−5), together with 12 known compounds (6−17), were isolated from the fresh leaves of Eucalyptus maideni. Structures of the new compounds were determined on the basis of spectroscopic analyses (HSQC, HMBC, and 1H−1H COSY), chemical degradation, and enzymatic hydrolysis. Of the tested compounds, only quercetin showed slight anti-herpes simplex virus 1 (HSV-1) activity
五个新的(+) - oleuropeic酸衍生物,eucalmaidins A-E(1 - 5),加上12种已知化合物(6 - 17),从新鲜叶中分离直杆蓝桉。在光谱分析(HSQC,HMBC和1 H- 1 H COSY),化学降解和酶水解的基础上确定了新化合物的结构。在测试的化合物中,只有槲皮素在体外显示出轻微的抗单纯疱疹病毒1(HSV-1)活性。
