Objective: To develop a quantitative reversed phase high performance liquid chromatography method for determination of R
S-goitrin in Banlangen preparations. Method: The samples were separated at 30 ℃ on a Shiseido C18 MG( 4.6 mm×250 mm
5 μm) column eluted with methanol-0.02% phosphate(7 ∶93) as the mobile phase. Flow rate was set at 1.0 mL ·min-1 and the detection wavelength was set at 245 nm. Result: The calibration curve of R
S-goitrin was linear within the range from 0.004 9 to 0.312 0 g ·L-1(r=1.000 0) and the average recovery was 99.0 %(RSD 2.04 %). Conclusion: The developed method was proved to be simple
reliable and useful by analysis of 26 batches of the samples purchased from different areas.
