4种姜黄属药材挥发油中莪术醇含量比较

目的 建立准确测定姜黄属4种中药材挥发油中莪术醇含量。方法 以高效毛细管柱序升温气相色谱法测定莪术醇的含量。结果 本法能准确测定莪术醇的含量，回收率为101．4％，RSD为0．4％，还测定了4种姜黄属药物（温郁金、姜黄，桂莪术，蓬莪术）中莪术醇的含量，发现4种药材中莪中醇的含量差异显著。结论 为姜黄属药材质量的分析控制提供可行的含量测定方法。

Comparison of curcumol contents in essential oil from four species of rhizoma Curcumae L.

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 performance capillary gas chromatography with sequential increase of temperature on a HEWLETT PACKARD 5890A gas chromatograph. Results The method can be used to determine curcumol with accuracy at a recovery of 101.4% and RSD of 0.40%. Conclusion The present study provided a satisfactory method for the determination 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.
