英文摘要：

[Objective]To synthesize polyphenols derivatives loading catechin from dehydroabietane. [Methods] Through nitration, reduction, condensation and oxidation reaction, derivatives bonding multiple catechins was synthesized from dehydroabietane as the starting material. [Result]The novel dimers of 12,18-diE（3,4-dihy- droxybenzylidyne） amino3-14-nitro 2e was successfully synthesized. [Conclusion]The structure of 2e was char- acterized by UV-Vis,IH NMR,13C NMR,IR,MS and elemental analysis.
