Two new anthraquinones, 3-hydroxy-6-hydroxymethyl-2,5-dimethylanthraquinone (1) and 6-hydroxymethyl-3-methoxy-2,5-dimethylanthraquinone (2), were isolated from the fermentation products of the endophytic fungus Phomopsis sp. Their structures were elucidated by spectroscopic methods, including extensive 1D and 2D NMR techniques. Compounds 1 and 2 were evaluated for their antimethicillin-resistant Staphylococcus aureus activity. The results showed that compounds 1 and 2 showed good inhibition with IZD of 14.2 ± 2.0 and 14.8 ± 2.2 mm, respectively. Compounds 1 and 2 were also tested for antioxidant activity; they show good activity with IC₅₀ values of 4.18 and 4.36 μg/mL, respectively.

两个新的蒽醌，3-羟基-6-羟甲基-2,5- dimethylanthraquinone（1）和6-羟甲基-3-甲氧基-2,5-二dimethylanthraquinone（2），从该内生真菌的发酵产物中分离拟茎点霉属. 它们的结构是通过光谱方法阐明的，包括广泛的 1D 和 2D NMR 技术。评估了化合物 1 和 2 的抗甲氧西林金黄色葡萄球菌活性。结果表明，化合物1和2显示出良好的抑制作用，IZD分别为14.2±2.0和14.8±2.2mm。还测试了化合物 1 和 2 的抗氧化活性；它们显示出良好的活性，IC ₅₀值分别为 4.18 和 4.36 μg/mL。
