摘要
目的:为 控制蓝芪 降糖胶囊 的质 量 建立 葛根 素 的 H P L C 方 法。方 法: 色谱 条 件为: O D S 柱,以甲醇 —0 .02 m ol/ L 磷酸 二氢钾(p H= 4)(25 ∶75 ) 为流 动 相,流 速 0 .8 ml/ m in ,检 测 波长 为 250n m 。结果:平 均回收 率99 .74 % , R S D= 1 .44 % 。结 论:此 方 法简 便、灵敏、准 确、重 复 性 好,其 它 组 分对测定无 干扰,可 用于该制 剂的质 量评价和 质量控 制。
Objective: To control the quality of Langi jiangtang capsules. The HPLC method of Puerarin was established. Methods: A chromatography method for the separation and determination of puerarin in the preparation was established, chromatography conditions: ODS column with methanol——0.02 mol/L potassium dihydroger phosphate (25∶75) as the mobil phase at 0.8ml/min flow rate, detection wavelength at 250nm. Results: The average recovery was 99.74%, with RSD 1.44%. Conclusion: The method is simple, sensitive, accurate and with a good reproducibility.
