TITLE: | |
摘要: | 目的:建立测定新扶正除疫颗粒中红景天苷和虎杖苷含量的方法。方法:采用反相高效液相色谱法。色谱柱为GRACE Alltima TMC 18,流动相为甲醇-水(15 ∶ 85,V/V,红景天苷)、乙腈-水(23 ∶ 77,V/V,虎杖苷),流速为1.0 mL/min,检测波长为275 nm(红景天苷)、306 nm(虎杖苷),柱温为25 ℃,进样量为10 μL。结果:红景天苷和虎杖苷检测进样量线性范围分别为0.99~10.89 μg(r=0.999 8)、0.046~1.196 μg(r=0.999 8);精密度、稳定性、重复性试验的RSD<2.0%;加样回收率分别为96.31%~99.44%(RSD=1.20%,n=6)、95.96%~99.73%(RSD=1.42%,n=6)。结论:该方法操作简单方便、结果准确可靠,适用于测定新扶正除疫颗粒中红景天苷和虎杖苷的含量。 |
ABSTRACT: | OBJECTIVE: To establish a method for the contents determination of salidroside and polydatin in new Fuzheng chuyi granule. METHODS: RH-HPLC was performed on the column of GRACE Alltima TMC 18 with mobile phase of methanol - water (15 ∶ 85,V/V,salidroside) and acetonitrile-water (23 ∶ 77,V/V,polydatin) at a flow rate of 1.0 mL/min, detection wavelength was 275 nm (salidroside) and 306 nm (polydatin), column temperature was 25 ℃, and the injection volume was 10 μL. RESULTS: The linear range was 0.99-10.89 μg for salidroside (r=0.999 8) and 0.046-1.196 μg for polydatin (r=0.999 8); RSDs of precision, stability and reproducibility tests were lower than 2.0%; recoveries were 96.31%-99.44% (RSD=1.20%,n=6) and 95.96%-99.73% (RSD=1.42%,n=6). CONCLUSIONS: The method is simple, accurate and reliable, and suitable for the contents determination of salidroside and polydatin in new Fuzheng chuyi granule. |
