Abstract:
AIM:To develop a high performance liquid chromatography (HPLC) coupled with electrospray ionization mass spectrometry (ESI-MS) and ultraviolet (UV) detector method for the acid-alkaline simultaneous determination of ten bioactive compounds, and analyze the effect of compatible medicinal plants on the concentration of components in Dahuang Fuzi Tang (DFT).
METHOD:The chromatographic separation was performed on a Hypersil BDS C18 analytical column by gradient elution with acetonitrile and formate buffer (containing 0.15% formic acid, V/V) at 25 °C with a flow rate of 1.0 mL·min(-1) and UV detection at 280 nm. Four of the ten compounds in DFT were identified and their MS fragments were elucidated by HPLC-ESI-MS, and the contents of the six compounds were determined by HPLC-UV.
RESULTS:All calibration curves showed good linear regression (r(2) ≥ 0.9990). The limits of detection and limits of quantification were 0.021-0.155 -g·mL(-1) and 0.076-0.520 -g·mL(-1), respectively. Overall precision RSD (intra-day and inter-day) were less than 2.96%, and the average recoveries were 98.35%-101.45%, with RSD ranging from 1.54% to 3.01% for the analytes.
CONCLUSION:The developed method can be applied for the quality control and provide analytical evidence on the chemical basis and combinational principles of DFT.
