摘要
用高效液相色谱法测定补骨脂及其中成药中补骨脂素和异补骨脂素含量。用甲醇－水（6：40，v／v）作流动相，在μ－BondapakC18柱上，两成分能较好地分离。用甲醇作提取溶剂，超声振荡提取30min，分析了市售补骨脂及3种含补骨脂的中成药，方法简便，精密度较高。
A HPLC method was established for the determination of psoralen and isopsoralen in Psoralea corytifolia L. and its preparations. Psoralen and isopsoralen can be separated on μ－Bondapak C15 column with a mobile phase of MeOH－H2O (6:4) and detected at 245nm. The optimum conditions based on experimental results was to extract the sample by MeOH in an ultrasonator for 30 min. The method is simple and accurate.
