Objective: To establish methods of thin layer chromatography (TLC) identification and content determination of Lespedeza cuneata. Method: Quality differentiation method was developed using TLC and with toluene-ethyl formate-formic acid (10 : 8 : 1) as the developing solvent. Using high performance liquid chromatography (HPLC)
content determination of quercetin was carried on Hypersil ODS2 C18(4.6 mm×200 mm
5 μm) column eluted with a mixture of acetonitrile-0.2% phosphate(20 : 80) as the mobile phase
and diodematrix detector was used as the detector. Result: The established TLC method could effectively isolate each component
and the established HPLC method could accurately determine the content of quercetin in L cuneata. Conclusion: The established methods of TLC and HPLC can be used to detect the quality of L. cuneata.
