Their structures were identified as negunfurol （1）, schensianol A （2）, artemine （3）, erivanin （4）, 1,5-diepi-artemin （5）, acetylartemin （6）, naphtho[1,2-b]furan-2（3H）-one, 6-（acetyloxy） decahydro-9a-hydroxy-3,Sa-dimethyl-9-methylene-（3S,3aS,5aS,6S,9aS, ghS） （7）, naphtho[1,2-b]furan-2（3H）-one, 6-（acetyloxy）- 3a,4,5,5a,6,7,8,9b-octahydro-8-hydroxy-3,Sa,9-trimethyl- （3S,3aS, SaR,6S, SS,9bS） （8）, isoerivanin （9）, harrelierin （10）, （11S）-1- oxoeudesm-4（14）-eno-13,6a-lactone （11）, 1-epi-dehydroisoeranin （12）, respectively. All of these compounds were isolated from Artemisia vestita for the first time, and compounds 1 and 2 were isolated from the genus Artemisia for the first time.展开更多
