Abstract: The urushiol diacetate was successfully separated by centrifugal rotation TLCon the silica gel coated with silver nitrate.The structure and configuration of key component of.urushiol (64.6%) were determined successfully by using 1H and 13C conventional method,DEPTtechnique,homo- and heteronuclear chemical shift correlation 2D-NMR,2D-J NMR,hftteronuclear relayed coherencetransfer 2D-NMR,and relaxation time T1 investigation.The as-signment of resonances for 1H and 13C were confirmed.There is plentyof evidence which shows that the key component of urushiol is 3-(8'Z,11'E,13'Z-pentadecatrienyl)catechol.The results show that RELAY 2D-NMR new technique can be successfully applied to determining the structure of complicated unknown compounds.
