摘　　要：测定保健食品中红景天甙的含量以控制产品质量。采用十八烷基硅烷键合硅胶柱；以乙腈-水（1：9）为流动相，流速为1.0mL／min，检测波长为280nm。结果表明红景天甙在0．4—4．0μg范围内呈线性关系，平均回收率（n=6）为98．96％（RSD=1.16％）。该方法简便、准确、重现性好，可用于保健食品中红景天甙的质量控制。To determine salidroside in health food for establishing a method of quality control, an ODS colunm was used with a mobile phase consisted of mixture of acetonitrile-water buffer（ 1： 9） ,flow rate was 1.0 mL/min, and detector wavelength was 280 nm. The linear range of salidroside was 0.4- 4.0 μg. The average recovery was 98.96% （ RSD = 1.16% ,n =6）. The method appeared to be simple,accurate with good reproducibility,and can be used to the quality control.
