ABSTRACT

Green analytical procedures replace harmful organic modifiers with green solvents without affecting chromatographic performance, enabling industries and research laboratories to develop green analytical methods. Benidipine hydrochloride (BEN) and Chlorthalidone (CHD) were used to treat hypertension. The literature indicates that no method for determining BEN and CHD combines RP-HPLC with green Analytical Quality by Design (AQbD) for long-term use. This study aimed to develop a green RP-HPLC for determining BEN and CHD by incorporating analytical quality by design with green chemistry principles. A central composite design was used for optimization, with 40% ethanol content and flow rate chosen as critical variables. Separation was achieved using Agilent Eclipse Plus (C18, 250 mm × 4.6 mm i.d, 5 μm) with a mobile phase of ethanol and potassium dihydrogen orthophosphate (orthophosphoric acid to 3.5) in a ratio of 40:60 v/v at 1 ml/min, detection wavelength at 230 nm. Retention times for CHD and BEN were 3.1 and 5.1 min, respectively. The concentration ranges for BEN and CHD were 3.2–4.8 μg/ml and 5.0–7.5 μg/ml, respectively. The proposed method was eco-friendly and assessed using green evaluation tools. Thus, AQBD and green technologies provide regular BEN and CHD analysis in pharmaceutical formulations without environmental impact.

采用设计分析质量同时评估抗高血压药物的环境友好型 RP-HPLC 方法

摘要

绿色分析程序用绿色溶剂替代有害的有机改性剂,而不影响色谱性能,使工业界和研究实验室能够开发绿色分析方法。盐酸贝尼地平(BEN)和氯噻酮(CHD)用于治疗高血压。文献表明,没有一种测定 BEN 和 CHD 的方法能够将 RP-HPLC 与绿色分析质量设计 (AQbD) 结合起来长期使用。本研究旨在通过将分析质量设计与绿色化学原理相结合,开发一种用于测定 BEN 和 CHD 的绿色 RP-HPLC。采用中心复合设计进行优化,选择 40% 的乙醇含量和流速作为关键变量。使用 Agilent Eclipse Plus(C18,250 mm × 4.6 mm 内径,5 μm),流动相为乙醇和正磷酸二氢钾(正磷酸为3.5),体积比为40:60 v/v,流速为1 ml/min,检测波长为230 nm。CHD 和 BEN 的保留时间分别为 3.1 分钟和 5.1 分钟。BEN 和 CHD 的浓度范围分别为 3.2–4.8 μg/ml 和 5.0–7.5 μg/ml。所提出的方法是生态友好的,并使用绿色评估工具进行评估。因此,AQBD 和绿色技术可在药物配方中定期进行 BEN 和 CHD 分析,而不会对环境造成影响。所提出的方法是生态友好的,并使用绿色评估工具进行评估。因此,AQBD 和绿色技术可在药物配方中定期进行 BEN 和 CHD 分析,而不会对环境造成影响。所提出的方法是生态友好的,并使用绿色评估工具进行评估。因此,AQBD 和绿色技术可在药物配方中定期进行 BEN 和 CHD 分析,而不会对环境造成影响。
