从蓝花黄芩内生真菌土曲霉(Aspergillus terreus) HQ100X-1发酵产物中分离得到2个新化合物[terrustone (1)和asperteretone G (2)], 10个已知化合物(3~12), terrustone (1)为具有4个连续手性中心的三羟基环戊酮类化合物, 它们的结构以及绝对构型是通过1D/2D NMR结合电子圆二色谱(ECD)计算来确定. 抗菌实验表明, 化合物rbrolide R (4)对金黄色葡萄球菌有一定的抑菌活性, 其最低抑菌浓度(MIC)值为2.5 μg/mL.

关键词: 蓝花黄芩, 土曲霉(Aspergillus terreus), 抗菌活性

Two new compounds, terrustone (1) and asperteretone G (2) together with ten known compounds were isolated from Scutellaria formosana endophytic fungus Aspergillus terreus HQ100X-1, terrustone (1) is a trihydroxycyclopentanone with four consecutive chiral centers. Their structures were determined by 1D/2D NMR data along with electrostatic circular dichroism (ECD) calculation for configurational assignment. Compound rbrolide R (4) showed antibacterial activity against Staphylococcus aureus with minimum inhibitory concentration (MIC) value of 2.5 μg/mL.

Key words: scutellaria formosana, Aspergillus terreus, antibacterial activity
