Abstract: | Dehydroandrographolide, andrographolide and geniposide are the main active constituents of many herbal medicines, e.g., Fructus gardeniae, Common Andrographis Herb. They are used as the markers to control the quality of such herbal medicines and their herbal preparations. In this paper, a simple and sensitive high-performance liquid chromatographic (HPLC) method coupled with photodiode array detection (DAD) and electrospray mass spectrometry (ESI/MS) were developed to determine the three compounds simultaneously in extracts of medicinal herbs and herbal preparations produced by different companies. The extracts were separated on a C18 reversed phase HPLC column, with a gradient solvent system, the time for the separation of the three target analytes was 10 min. The abundance ions were recorded using selected ion monitoring (SIM) mode with m/z 297.3, 297.3 and 411.1 for dehydroandrographolide, andrographolide and geniposide, respectively. The limit of detection for dehydroandrographolide, andrographolide and geniposide were 20, 30 and 150 ng mL−1, respectively. The proposed method was successfully applied to the determination of the contents of the compounds in related to medicinal herbs and preparations. |
