Object To develop a new method for the determination of curcumol in essential oil from rhizoma Curcumae L. . Methods The contents of curcumol were determined by high performa nce capillary gas chroma tog raphy with sequential increase of temperature on a HEWLET T PACK ARD 5890A gas chroma tog raph. Results The method can be used to determine curcumol wi th accuracy at a recovery of 101. 4% and R SD of 0. 40% . Conclusion The present study provided a satisfactory method for the determinatio n of curcumol , and it was found that its contents in four different species (C. wenyujin, C. longa, C. aeruginose, and C. kwangsiensis) were markedly different.
