| 摘 要： | 应用高效液相色谱法,测定了不同产地补骨脂中补骨脂素和异补骨脂素的含量.色谱柱为Kromasil-C18(4.6 mm×250 mm,5μm),流动相:甲醇-水(45: 55),检测波长:245 nm,流速:1.0 ml/min,柱温:35℃.结果:补骨脂素在0.0448～0.448μg(r＝0.9999)范围内、异补骨脂素在0.0356～0.356μg(r＝0.9997)范围内线性关系良好,补骨脂素和异补骨脂素平均回收率分别为98.69%(RSD＝1.97%)和101.09%(RSD＝3.06%).

| Abstract: | OBJECTIVE: To study the psoralen and isopsoralen content in Psoralea corylifolia from different habitats. METHOD: C18 column was used. Mobile phase was methanol-water (45:55). The detection wavelength was at 245nm and the flow rate was 1.0 ml/min. RESULT: The linearity was obtained over the range of 0.448 to approximately 0.448 microg (r = 0.9999) for psoralen, 0.356 to approximately 0.356 microg = 0.997) for isopsoralen. CONCLUSION: The contents of psoralen and isopsoralen in Psoralea corylifolia from different habitats have no obvious difference. |
