Two new chromone derivatives ( and ), and two known compounds ( and ) were isolated from the rhizosphere soil fungus . Their planar structures and absolute configurations were determined by extensive spectroscopic analysis and electronic circular dichroism (ECD) calculations. Additionally, all the isolated compounds were evaluated for their antibacterial activity against , , and , but no obvious activity was observed at a concentration of 128 μg/mL.
从根际土壤真菌 中分离得到两个新的色酮衍生物（ 和 ）和两个已知化合物（ 和 ）。通过广泛的光谱分析和电子圆二色性（ECD）计算确定了它们的平面结构和绝对构型。此外，还评估了所有分离得到的化合物对 、 、 和 的抗菌活性，但在 128μg/mL 的浓度下没有观察到明显的活性。
