ABSTRACT

Objective:

To qualitatively and quantitatively analyze the terpene-conjugated curcuminoid compound- Bisabolocurcumin ether (BCE) in Curcuma species.

Methods:

UPLC-Q-TOF-MS/MS was used to establish a qualitative analysis of BCE, and its distribution in Curcuma species was studied. UPLC was used to establish quantitative analysis of BCE and three main curcuminoids in three Curcuma species (Rhizoma Curcumae Longae, HuangsiYujin, Curcuma phaeocaulis), in order to study the difference of BCE content in different Curcuma species and its content difference with other curcuminoids.

Results:

In the qualitative analysis, by analyzing the primary, secondary pyrolysis fragments and the cracking law of BCE, it was found that only Jianghuang and HuangsiYujin contained it, but BCE could not be detected in the PengEzhu. In the quantitative analysis, BCE and the three main curcuminoids had good linear relationship in their linear range (r ≥ 0.999 3); The average recovery rates were in range of 99.407%-113.631%, and RSD < 4%. It was found that the content of three curcuminoids in Jianghuang were significantly higher than the other two herbs, and the content of BCE in the three herbs was very different. The BCE content in Jianghuang was four times than that of HuangsiYujin.

Conclusion:

The qualitative and quantitative analysis methods established in this study can provide reference for the discovery and analysis of more novel BCE structure’s compounds, and provide a basis for improving the quality standards of Curcuma species.
