ABSTRACT

Objective:

To establish an ultra-high performance liquid chromatography coupled with triple quadrupole mass spectrometry (UHPLC-QqQ MS) method for the simultaneous determination of twelve components (wogonoside,baicalin,wogonin,chrysin,uteolin,caffeic acid,acetylcorynoline,corynoline,protopine,salicylic acid,uracil and adenosine) in Pudilan Xiaoyan oral liquid.

Method:

The analysis was performed on an Agilent Extend C18 column(3.0 mm×150 mm,3.5 μm),with a gradient elution by using the mobile phase of methanol-water(0.1%formic acid). The flow rate was 0.3 mL·min-1. Triple quadrupole mass spectrometry, electrospray ionization source (ESI),DMRM mode, and positive and negative ions alternate mode were adopted.

Result:

The 12 reference substances had a good specificity. Wogonoside,baicalin,wogonin,chrysin,uteolin,caffeic acid,acetylcorynoline,corynoline,protopine,salicylic acid,uracil and adenosine showed good linear relationships within the range of 0.062 24-16.24,33.95-530.4,0.013 64-3.558,0.001 157-0.302 4,0.001 199-0.313 0,0.014 64-3.821,0.000 739 5-0.038 59,0.060 83-3.174,0.002 443-0.637 4,0.021 80-1.138,0.022 99-6.000,0.006 046-1.578 μg·L-1,with a good precision,stability and repeatability. And the average recoveries were 98.9%,100.2%,106.9%,100.8%,101.7%,99.3%,94.6%,100.0%,100.5%,103.4%,96.8%,98.1%.

Conclusion:

This method was simple,sensitive and reliable. It laid a foundation to promote the quality control standard of Pudilan Xiaoyan oral liquid.
