Abstract: Molecular structure of the δ-Damascones were defined by 13C-NMR technique (BB, DEPT, Gated decoupling). The influence space configuration and shielding effect on δC was discussed, and primary characteristic parameters distinguishing isomer(Ⅰ) from(Ⅱ) have been obtained.

Key words: δ-Damascone, 13C-NMR
