TITLE: | |
摘要: | 目的:建立测定补骨脂-青龙衣酊中补骨脂素含量的方法。方法:采用高效液相色谱法。色谱柱为Shim-pack VP-ODS C18,流动相为甲醇-水(60 ∶ 40,V/V),流速为0.8 ml/min,检测波长为246 nm,柱温为25 ℃,进样量为20 μl。结果:补骨脂素的检测质量浓度线性范围为2.49~39.90 μg/ml;精密度、稳定性、重复性试验的RSD<2.00%;加样回收率范围为97.23%~100.58%,RSD=1.17%(n=6)。结论:该方法快速简便、准确可靠,可用于补骨脂-青龙衣酊中补骨脂素的含量测定。 |
ABSTRACT: | OBJECTIVE:To establish a method for the content determination of psoralen in Psoralea-pericarpium juglates liniment. METHODS: HPLC was performed on the column of Shim-pack VP-ODS C18 with mobile phase of methanol-water (60 ∶ 40,V/V)at a flow rate of 0.8 ml/min, detection wavelength was 246 nm,column temperature was 25 ℃, and injection volume was 20 μl. RESULTS: The linear range of psoralen was 2.49-39.90 μg/ml; RSDs of precision, stability and reproducibility tests were lower than 2.00%; recovery was 97.23%-100.58% (RSD=1.17%,n=6). CONCLUSIONS:The method is fast, simple, accurate and reliable, and can be used for the content determination of psoralen in Psoralea-pericarpium juglates liniment. |
