Thirteen new sativene sesquiterpenoids ( and -), one new natural product (), and 16 known compounds (-) were isolated from the endophytic fungus S27. Their structures were elucidated by extensive spectroscopic analysis, NMR and ECD calculations, and X-ray crystal diffractions. Compound represented the first example of sativene sesquiterpenoids with a 6/5/3/5-caged tetracyclic ring system. All obtained compounds were evaluated for their plant-growth regulatory activity. The results showed that , , , , , , , , , , and could suppress the growth of , while , , , , , and showed promoting effects. Among them, compound showed the most potent plant-growth inhibitory activity, which is obviously superior to that of the marked herbicide glyphosate.
从内生真菌 S27 中分离得到了 13 种新的倍半帖烯类化合物（-），1 种新天然产物（）和 16 种已知化合物（-）。通过广泛的光谱分析、NMR 和 ECD 计算以及 X 射线晶体衍射确定了它们的结构。化合物 代表了具有 6/5/3/5 笼状四环体系的倍半帖烯类化合物的首例。所有获得的化合物均进行了植物生长调节活性评估。结果表明， 、 、 、 、 、 、 、 、 和 可抑制 的生长，而 、 、 、 、 和 则表现出促进作用。其中，化合物 表现出最强的植物生长抑制活性，明显优于标记除草剂草甘膦。
