|
A UPLC method for the simultaneous determination of seven compounds was established for the quality control in H. cordata. The UPLC was performed on a C18 HSS T3 2.1 × 100 mm, 1.8 μm column during a 13 minute gradient elution of 0.2% aqueous acetic acid and acetonitrile with the flow rate of 0.2 mL/min at 30 oC.The UPLC method was validated according to the ICH guideline of analytical procedures with respect to precision, accuracy, and linearity. The limit of determination and quantitation for the seven compounds were 0.01-0.09 and 0.03-0.28 μg/mL, respectively. The calibration curves of all seven compounds showed good linearity (r2 > 0.999). The intra-day and inter-day the RSD values used to evaluate the precision of analysis were less than 0.9%. The recoveries of quantified compounds ranged from 98.63 to 103.85%. The developed UPLC method was found to be effective, convenient and sensitivity for quantitative analysis of seven compounds in H. cordata. This work could be provided a baseline source for quality control of H. cordata.
