Abstract

Abstract Urushiol diacetate, derived from urushiol, a major component of the sap of Japanese lac trees ( Rhus vernicifera), was separated into 14–16 peaks by high-performance liquid chromatography on 10% silver nitrate-coated LiChrosorb Si-60 and LiChroprep Si-60 columns (15 cm × 4 mm I.D. and 60 cm × 2.2 cm I.D., respectively) using benzene-chloroform (4:1) as eluent. Peaks were identified from UV and mass spectroscopic data, indicating that the separation of urushiol diacetate was due to the difference in the degree of unsaturation of the side-chain. Hexanol-1 was used for slurry packing the column.
