目的:深入研究狗脊中的化学成分。方法:采用柱色谱和高效液相色谱法分离纯化狗脊中的化学成分,并采用质谱和核磁共振技术鉴定其结构。结果:1个新的酚性成分,即4-O-咖啡酰-D-葡萄糖被分离得到,其结构通过1D,2D NMR和ESI-MS鉴定。结论:4-O-咖啡酰-D-葡萄糖首次从狗脊中分离得到,该化合物为新的酚性化合物。

Objective： To study the chemical constituents from Cibotium batometz. Method： Column chromatograph and HPLC were used to isolate and purify the compound, and the structure was elucidated on the basis of MS and NMR spectroscopic meth- ods. Result： A new phenolic compound, 4-O-caffeoyl-D-glucopyranose, has been isolated from the rhizome of C. barometz. The struc- ture of the new compound was elucidated on the basis of chemical and spectroscopic methods, including intensive 1D, 2D NMR and ESI-MS data analysis. Conclusion： 4-O-caffeoyl-D-glucopyranose was a new phenolic compound.
