摘 要: | 目的:建立HPLC测定肾乐胶囊中橙皮苷含量的方法。方法:采用HPLC法对肾乐胶囊中橙皮苷进行含量测定。测定条件:采用Diamonsil C18色谱柱(250 mm×4.6 mm,5μm),流动相为甲醇-水(40∶60),检测波长:283 nm,流速:1.0mL.min-1,柱温:35℃。结果:在本法条件下,橙皮苷与其他杂质峰分离良好,进样量在8.544~85.44 mg.mL-1与峰面积呈良好的线性关系(r=0.999 9),平均加样回收率为101.6%,RSD为0.54%(n=6)。三个批次的肾乐胶囊中橙皮苷的平均含量为2.75 mg.g-1。结论:采用该方法测定肾乐胶囊中的橙皮苷,简便易行,结果准确,可作为肾乐胶囊的质量控制方法。

Abstract: | Objective: To determine the content of hesperidin in Shenle capsule by HPLC. Methods: An HPLC method was used with Diamonsil C18 column (250 mm×4.6 mm, 5μm) and the mobile phase consisted of methanol-water (40 : 60). The flow rate was 1.0 mL-min-1, the detection wavelength was 283 nm and column temperature was 35℃. Results: The calibration curve was linear in the range of 8.544 - 85.44 mg-mL1 (r = 0.999 9). The average recovery was 101.6% and the RSD was 0.54% (n = 6). The average content of hesperidin in Shenle capsule was 2.75 mg. g-1. Conclusion: This method is accurate and feasible, and it can be applied as the quantitative method of hesperidin in Shenle capsule. |
