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)A,V=1365．67(18) A3,Z=4,Dc=1．354 mg／m3．F(000)=592,μ=0．101 mm-1
The compounds of 8β-hydroxyeremophil-7 (11) -ene-12,8α (4β, 6α) -diolide were isolated from the whole plant of Scutellaria barbata by chromatography and crystallization Structural identification was performed by mass spectroscopy, proton nuclear magnetic resonance spectroscopy and carbon spectroscopy, proton-proton correlation spectroscopy, heteronuclear multistage spectroscopy and heteronuclear multineel correlation spectroscopy. The single crystal was characterized by X-ray diffraction. The crystal belongs to the orthorhombic system with space group P212121. The unit cell parameters are a = 6.8519 (5), b = 10.7191 (8) and c = 18. 5942 (14) A, V = 1365.67 (18) A3, Z = 4, Dc = 1.354 mg / m3. F (000) = 592, μ = 0.101 mm-1
