Abstract:
HPLC analysis was performed on a Phenomenex PS C₁₈（4.6 mm×250 mm, 5 μm）column using methanol -0.2% formic acid (30:70) at a flow rate of 0.8 mL·min⁻¹. The column temperature was 30 °C and the detection wavelength was set at 335 nm. The injection volume was 10 μL. The HPLC fingerprint of Desmodium styracifolium was established with 10 common peaks, and 5 of them were identified as vicenin-1, schaftoside, isoorientin, isoschaftoside and isovitexin, respecivetly. The fingerprints of 21 batches of D. styracifolium samples were analyzed with similarity evaluation, cluster analysis, principal component analysis and partial least squares discriminant analysis. There was no significant difference among the quantitative results of these five ingredients verified by external standard method (ESM) and quantitative analysis of multi-components by single marker (QAMS) method. The application of fingerprint, pattern recognition combined with QAMS can provide more comprehensive references for the quality control and evaluation of D. styracifolium.
