Abstract: The urushiol diacetatcs have been successfully separated on the silica gel coated with silver nitrate by centrifugal rotation TLC. The structure and configuration of key component of urushiol (64.4%) were determined successfully by 1H and 13C conventional methods, DEPTtechnique, homo and beleronuclcar chemical shift correlation 2D-NMR, 2D-JNMR, helcronuclear relayed coherence transfer 2D-NMR, and relaxation time T1 investigation. The assignment of resonances for 1H and 13C were confirmed. Plenty of cvidence shows that the key component of urushiol is 3-(8'Z, 11'E, 13'Z-pentadccatrienyl) catechol. The results show that RELAY 2D-NMR new technique can be successfully applied to determining the structure of complicated unknown compounds.
