研究蒿属植物毛莲蒿地上部分倍半萜类化学成分, 通过硅胶柱色谱、反相硅胶柱色谱、制备高效液相色谱等色谱方法分离得到12个倍半萜类成分, 经多种波谱方法鉴定其结构, 分别为negunfurol (1), schensianol A (2), artemine (3), eudesm-4(14)-en-12-oic acid, erivanin (4), 1,5-diepi-artemin (5), acetylartemin (6), naphtho[1,2-b]furan-2(3H)-one,6-(acetyloxy)-decahydro-9a-hydroxy-3,5a-dimethyl-9-methylene-(3S,3aS,5aS,6S,9aS,9bS) (7), naphtho[1,2-b]furan-2(3H)-one,6-(acetyloxy)-3a,4,5,5a,6,7,8,9b-octahydro-8-hydroxy-3,5a,9-trimethyl-(3S,3aS,5aR,6S,8S,9bS) (8), isoerivanin (9), barrelierin (10), (11S)-1-oxoeudesm-4(14)-eno-13,6α-lactone (11), 1-epi-dehydroisoeranin (12)。其中化合物1和2为首次从蒿属植物中分离得到, 其它化合物均为首次从毛莲蒿中分离得到。
