Traditional mass spectrometers are often perceived as being too costly and complicated for routine use in QC labs, but this is no longer the case. Compact mass detectors that are easy to use and which integrate into existing LC workflows are now available and provide unique benefits for the detection of weak UV absorbers and for resolving analytes from matrix interferences in herbal medicinal products [1,2]. In this poster we illustrate how mass detection provides significantly improved selectivity for the analysis of parthenolide – a biologically important compound found in Feverfew herb that has a very poor natural UV chromophore [3,4] – in Feverfew raw materials and complex multi-herb medicinal products. These benefits are illustrated in the figure below, where the presence of parthenolide in a multi-herb dietary supplement is obscured by the presence of a strongly UV absorbing interference at the same retention time. Mass detection provides enhanced selectivity for parthenolide, allowing for accurate detection and quantification. By using this approach, parthenolide content was measured at 0.45 mg/serving in the aforementioned supplement.
