To establish a TLC identification method and the content determination of paeoniflorin in material benchmark of Huangqi Guizhi Wuwutang.
Thin-layer chromatography was employed for the identification of Astragali Radix (Astragalus root), Cinnamomi Ramulus (cinnamon twig), Paeoniae Radix Alba (white peony root) and Zingiberis Rhizoma Recens (fresh ginger) in material benchmark of Huangqi Guizhi Wuwutang. The quantitative analysis of paeoniflorin was performed by high performance liquid chromatography (HPLC) on a Thermo Hypersil GOLD C18 column (4.6 mm × 250 mm, 5 μm). The mobile phase was acetonitrile-0.1% phosphoric acid solution (14:86) with isocratic elution; the flow rate was 1.0 mL·min-1, the detection wavelength was 230 nm, and the column temperature was 25 ℃.
The linear range of paeoniflorin was 148.00-2 368.00 μg·mL-1 (r = 0.999 9). The average recovery of paeoniflorin was 98.48% (RSD = 0.95%).
The established method is sensitive, simple, reliable and suitable for the quality control in the research and development of the classic formula Huangqi Guizhi Wuwutang.
