摘要
OBJECTIVE: To establish a quantitative method for calceolarioside B in Caulis Akebiae. METHOD: The samples were separated at 35 degrees C on a Phenomenex Luna C18 column eluted with methanol-water-phosphoric acid (35: 65: 0.05) as mobile phase. Flow rate was at 1.0 mL x min(-1) and the detection wavelength was at 330 nm. RESULT: The calibration curve was linear over the range from 0. 04 to 0. 86 g (r = 0. 9998) and the average recovery was 97.2%. 39 Crude drug materials collected from different areas were determined and the contents of calceolarioside B in Caulis Akebiae were fluctuated from 0. 021% to 0. 745%. CONCLUSION: The method is simple and repeatable and could be used for the quality control of Caulis Akebiae.
