Abstract: A rapid and sensitive high-performance liquid chromatographic (HPLC) method had been developed and validated for the analysis of three main ingredients in analgesic bacteriostatic gel. Hydroxy-α-sanshool (HAS), hydroxyl-β-sanshool (HBS) and hydroxy-γ-sanshool (HRS) were separated on a Thermo Hypersil GOLD C18 column (150 mm × 4.6 mm, 5 μm) with gradient elution system. The mobile phase consisted of acetonitrile-water (v/v) with a flow rate of 1.0 mL/min and UV detection was performed at 270 nm. The method was validated according to the Chinese Pharmacopeia (2015). Linearity (r > 0.9990) was observed over the concentration ranges of 3.24–58.32, 0.656–11.81 and 0.304–5.48 mg/L for HAS, HBS and HRS. The average recovery for HAS, HBS and HRS was 96.9%, 97.2% and 97.9%. The method was found simple and rapid, which can be suitable for the determination of the three main ingredients in analgesic bacteriostatic gel.
