从毛蒿（Artemisia vestita）中分离得到4个新的倍半萜类化合物，命名为蒿素D-G（1-4）和3个已知的倍半萜类化合物（5-7）。这些新化合物的结构是基于广泛的光谱数据分析确定的。此外，电子圆二色性数据确定了新化合物的绝对构型。以小菜蛾3龄幼虫和3种植物病原真菌为试虫，测定了分离菌株的拒食活性和抑菌活性。化合物1-7具有一定的拒食活性，化合物1-4和6-7具有一定的抑菌活性。
Four new sesquiterpenoids, named artemivestinolide D-G (1-4) and three known sesquiterpenoids (5-7), were isolated from Artemisia vestita. The structures of these new compounds were determined based on extensive spectroscopic data analyses. Furthermore, the electronic circular dichroism data determined the absolute configurations of the new compounds. The antifeedant and antifungal activities of the isolates were evaluated against third-instar larvae of Plutella xylostella and three plant pathogenic fungi. Compounds 1-7 showed moderate antifeedant activities and compounds 1-4 and 6-7 exhibited antifungal activities.
