Objective: To establish the HPLC fingerprint chromatog. of Lemai granules and determine the content of six compoundsMethod: HPLC-DAD fingerprints of Lemai granules were determined with high-performance liquid chromatog. on Phenomenex Luna C18 column (4.6 mm×250 mm, 5μm) with the gradient solvent system consisting of methanol (A) and water (B).The flow rate was 1.0 mL·min-1; the detection wavelength was set at 210 nm, and the column temperature was maintained at 30°C.Result: Fingerprints of Lemai granules were obtained.A total of 16 chromatog. peaks were common peaks, and the fingerprints of 10 batches of Lemai granules were identified with high similarity of fingerprints.Six chem. components were identified and their contents were determinedConclusion: The establishment of HPLC fingerprints provide a scientific basis for specifying medicinal resources and quality evaluation of this formula.
