[摘要] 目的 采用反相高效液相色谱法,建立同时测定补骨脂提取物中补骨脂素、异补骨脂素和补骨脂酚含量的方法。 方法 采用Epic C18(250 mm×4.6 mm,5 μm)色谱柱;流动相:甲醇-水,梯度洗脱;流速:1.0 mL/min;柱温:30℃;检测波长250 nm。 结果 该法测定补骨脂素、异补骨脂素和补骨脂酚分别在0.0563~0.3379、0.0523~0.3139、0.1280~0.7680 μg范围内线性关系良好,相关系数均为0.9999。平均加样回收率分别为100.66%(n=6)、RSD=1.77%,100.43%(n=6)、RSD=1.45%和99.41%(n=6)、RSD=1.63%。 结论 本方法简便、准确、灵敏、重复性好,可作为补骨脂提取物中补骨脂素、异补骨脂素和补骨脂酚的含量控制方法。

[Abstract] Objective To determine psoralen, isopsoralen and bakuchiol from the extract of Psoralea corylifolia by RP-HPLC. Methods The contents of paoralen, isopsoralen and bakuchiol were determined on the Epic C18 (250 mm×4.6 mm, 5 μm) column, with methanol: water in gradient elution manner. The flow rate was 1.0 mL/min, the column temperature was maintained at 30℃, and the detection wavelength was set up at 250 nm. Results The linear ranges of paoralen, isopsoralen and bakuchiol were 0.0563-0.3379, 0.0523-0.3139 and 0.1280-0.7680 μg (r=0.9999). The average recovery of paoralen, isopsoralen and bakuchiol were 100.66%, 100.43% and 99.41%, RSD were 1.77%, 1.45% and 1.63% (n=6). Conclusion The method is convenient, accurate sensitive and repeatable, and can be used in the content control method of psoralen, isopsoralen and bakuchiol in extract of Psoralea corylifolia.

補骨脂是中医、维吾尔医常用药材,临床应用广泛。补骨脂为豆科植物补骨脂(Psoralea corylifolia L.)的干燥成熟果实。维吾尔医认为本品性二级干热,味辛、苦。功能生干生热,清除异常黏液质,赤肤发泡,增加色素,净血解毒,祛风止痒,燥湿除疹,杀驱肠虫等。主治湿寒性或黏液质性疾病,如白癜风,麻风,皮肤瘙痒,各类湿疹,肠道生虫等。中医认为补骨脂味辛、苦、温,归肾、脾经,具有温肾助阳,纳气平喘,温脾止泻之功效;外用消风祛斑。用于肾阳不足,阳痿遗精,遗尿尿频,腰膝疼痛,肾虚作喘,五更泄泻;外治用于皮肤病和白癜风,斑秃等[1-2]。《中国药典》(2015版)中收载的含补骨脂的中成药就有40种,临床医师处方中应用补骨脂更广泛,《卫生部药品标准-维吾尔药分册》收载的含补骨脂的白癜风治疗制剂有9种[2]。
