title: [Quantitative analysis of synephrine in zhishi injection by RP-HPLC].
abstract: A reversed phase HPLC method was developed for the determination of synephrine in Zhishi Injection using methanol-water (1:1) containing sodium 1-pentane sulfonate (3.5%, G/V) and acetic acid (0.1%, V/V) as the mobile phase with UV detoction at 275nm. Linear response was obtained in the range of 8-64 micrograms/ml (r = 0.9998), the absolute recovery was 96.2-103.4%, and RSD 2.7%-6.0% (n = 7).
