Objective: To study the content of active principle and main content in Radix Cortonis Crassifolii in order to provide some academic basis for quality criterion of Radix Cortonis Crassifolii. Method: The method of HPLC was used to determine the content of chettaphaninⅡ in different batches. The method was established on a Phenomenex Luna (2) C18 column(4.6 mm×250 mm
5 μm) with the mobile phase on stepwise gradient elution of acetonitrile-0.1%H3PO4 and the temperature at 30 ℃
the detection wavelength was set at 355 nm. Result: The calibration curves of chettaphaninⅡ was Y=2×106X-166 725 (r=0.999 8)
showing good linearity in the range of 0.255-7.65 μg.The content of Radix Cortonis Crassifolii was 0.472-1.069 mg·g-1. Conclusion: This method is accurate
sensitive
stable and reliable and can be used for quality control of Radix Cortonis Crassifolii.
