中文摘要：
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20μl。结果：补骨脂素的检测质量浓度线性范围为2.49~39.90μg/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。
英文摘要：
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 20μl. 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.
