The aerial parts of Artemisia myriantha have afforded one new fulvenoguaianolide and four dimeric guaianolides in addition to seven known guaianolides. The structures of all the compounds were elucidated by 2D NMR. It is speculated that the dimeric guianolides are formed via Diels-Alder type reactions of fulvenoguaianolide derivatives.
多花蒿的地上部分除了含有七种已知愈创木烷型倍半萜内酯外,还提供了一种新的富烯愈创木烷型倍半萜内酯和四种二聚愈创木烷型倍半萜内酯。所有化合物的结构均通过二维核磁共振光谱进行了阐明。据推测,二聚愈创木烷型倍半萜内酯是通过富烯愈创木烷型倍半萜内酯衍生物的狄尔斯-阿尔德型反应形成的。
