【摘要】 综合利用硅胶、凝胶、MCI等柱层析方法从毛萼香茶菜中进行分离、纯化到10个二萜化合物,结合MS、1H NMR、13C NMR和相关文献资料分别鉴定为6-乙酰基-毛萼晶B(1)、毛萼晶O(2)、12-hydroxydehydro-abietic acid(3)、Neorabdosin(4)、毛萼晶D(5)、毛萼晶E(6)、毛萼晶B(7)、毛萼晶N(8)、Coetsoidin A(9)、毛萼晶L(10)。其中化合物1为新天然产物,3为首次从该植物中分离。更多还原

【Abstract】 Ten diterpene compounds were isolated from Isodon erioealyx in Guizhou by the comprehensive utilization of silica gel,Sephadex LH-20 and MCI column chromatography. Their structures were identified on the basis of spectrum data and literature. All compounds were elucidated as 6-acetyl-Maoecrystal B(1),Maoecrystal O(2),12-hydroxydehydro-abietic acid(3),Neorabdosin(4),Maoecrystal D(5),Maoecrystal E(6),Maoecrystal B(7),Maoecrystal N(8),Coetsoidin A(9),Maoecrystal L(10),respectively. Compound 1 was a new natural product. Compound 3 was firstly isolated from I. erioealyx.更多还原
