| Abstract: |
| 8β-hydroxyeremophil-7(11)-ene-12,8α(4β,6α)-diolide was isolated from the Ligularia intermedia and char- acterized by MS, multi NMR and X-ray single crystal diffraction. Its crystal structure was determined as in a orthorhombic type, with space group P212121 with a=6.8519(5), b=10.7191(8), c=18.5942(14) oA, V =1365.67(18) oA3, Z=4, and the calculated density is 1.354 mg/m3. F(000)=592, μ=0.101 mm-1. |

| 摘要: |
| 运用层析法、结晶法从狭苞橐吾全草中分离得到艾里莫芬烷型
倍半萜8β-hydroxyeremophil-7(11)-ene-12,8α(4β,6α)-diolide化合
物，并通过质谱、核磁共振氢谱和碳谱、氢核-氢核相关谱、异核多
量子相干谱和异核多键相干谱进行结构鉴定. 其单晶经X射线衍射
测试表明，其晶体属正交晶系，空间群为P212121，晶胞参数为:
a=6.8519(5)，b=10.7191(8)，c=18.5942(14) oA, V = 1365.67(18)
oA 3，Z=4，Dc=1.354 |
