ABSTRACT
AIM:
To develop a new method of gas chromatography for simultaneously determining curcumol contentin and β-elemene in Zedoary Turmeric Oil.METHODS:
Separation and quantification were achieved on a quartz capillary column(30 m×0.32 mm)of PEG with a column temperature gradient from 80℃(holding for 7 min)to 140℃ at a rate of 20℃/min,holding for 15 min,taking N2 as loader.The temperature for gasification was 210℃;the temperature for detection was 200℃;the compressive stress of column was 0.27 MPa.RESULTS:
Under the optimal chromatographic conditions,the linear range of curcumol contentin was within 0.230 5-3.23 mg/mL and the linear range of the β-elemene was within 0.237 5-3.33 mg/mL.The average recovery of curcumol contentin was 100.4% with a relative standard deviation(RSD)of 1.1% and β-elemene was 100.2% with a RSD of 2.2%.CONCLUSION:
The results show that it is a simple,rapid,accurate and sensitive method which is suitable for analysis of complex component(curcumol contentin and β-elemene)in Zedoary Turmeric Oil at the same time.
