ABSTRACT
Objective To establish an HPLC method for the content determination of protodioscin and diosgenin in Dioscoreae Hypoglaucae Rhizoma from different habitats.Methods The chromatographic separation was performed on an Agilent C18 column (4.6 mm×150 mm, 5μm) with mobile phase of acetonitrile-water solution with gradient elution at the flow rate of 0.8 mL/min; the detection wavelength was 208 nm; the column temperature was 30℃; the injection volume was 20μL.Results Protodioscin showed a good linear relationship among the range of 1.73–8.64 μg (r=0.999 6), with the average recovery of 101.98% (RSD=1.53%); Diosgenin showed a good linear relationship among the range of 1.03–8.20μg (r=0.999 1), with the average recovery of 101.60% (RSD=2.41%). The contents of protodioscin and diosgenin in Dioscoreae Hypoglaucae Rhizoma from 10 different habitats were in the range of 0.89%–2.24% and 0.75%–3.22%, respectively.Conclusion The method is simple, accurate and with repeatability, which can be used as quality control method of Dioscoreae Hypoglaucae Rhizoma.
