目的 对姜黄属药材中萜烯缀合姜黄素类化合物（BCE）进行系统的定性、定量分析。方法 利用超高效液相色谱-飞行时间质谱法（UPLC-Q-TOF-MS/MS）建立针对BCE的定性分析，研究其在不同姜黄属药材中的分布情况；再利用UPLC法建立对姜黄、黄丝郁金及蓬莪术中的BCE及3个主要姜黄素（姜黄素、脱甲氧基姜黄素和双脱甲氧基姜黄素）的定量分析，研究BCE在不同姜黄属药材中的含量差异及其与其他姜黄素类成分的含量差异。结果 在定性研究中，通过对BCE一级、二级裂解碎片及质谱裂解规律的分析，发现只有姜黄、黄丝郁金中含有该类成分，而蓬莪术中未能检测出BCE；在定量研究中，BCE及3个主要姜黄素在线性范围内均具有良好的线性关系（r≥0.9993）；平均回收率在99.407%～113.631%，RSD<4%，测定发现姜黄中的3个姜黄素类成分明显高于另外2种药材，且BCE在3种药材中含量差异较大，姜黄中的BCE含量是黄丝郁金的4倍。结论 本研究建立的定性、定量分析方法能够为更多BCE类新颖结构化合物的发现和分析提供借鉴，并为提升姜黄属药材的质量标准提供依据。

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.
