Abstract

Background: Hypericin (HYP) is a natural compound widely used as a food supplement. The encapsulation of HYP into nanosystems, such as nanostructured lipid carriers (NLC), is a promising strategy for delivering this lipophilic molecule and protecting it from degradation.

Objective: This study aims to develop and validate an analytical method to quantify the encapsulation efficiency of HYP in NLC.

Method: A reverse-phase high-performance liquid chromatography (HPLC) method was developed and validated according to the International Conference on Harmonization (ICH) guide Q2 (R1). NLC was prepared through the ultrasonication method, and HYP encapsulation efficiency was evaluated using the validated method.

Results: Separation was achieved using an isocratic mobile phase composed of acetonitrile, methanol, and ammonium acetate buffer (10 mM, pH 5.0) (54:36:10, v/v/v) and a reverse stationary phase. The specificity, linearity, precision, accuracy, and robustness of the method were assessed and confirmed during the validation. Furthermore, the validated method was able to determine the encapsulation efficiency of HYP in NLC.

Conclusions: The HPLC method was validated, and the results indicated the ability of NLC to deliver HYP compounds for further application as a food supplement.

Highlights: HYP is used as a food supplement and for photodynamic therapy (PDT). The developed method was specific, linear, precise, accurate, and robust. NLCs showed a high ability to encapsulate HYP.

纳米结构脂质载体中金丝桃素定量的创新色谱方法的验证。

背景：金丝桃素是一种广泛用作食品补充剂的天然化合物。将HYP封装到纳米系统中，如纳米结构脂质载体（NLC），是递送这种亲脂性分子并保护其免受降解的一种很有前途的策略。目的：本研究旨在开发和验证一种定量HYP在NLC中包封效率的分析方法。方法：根据国际协调会议（ICH）指南Q2（R1），开发并验证了反相高效液相色谱（HPLC）方法。通过超声法制备了NLC，并使用验证的方法评估了HYP的包封效率。结果：使用由乙腈、甲醇和乙酸铵缓冲液（10 mM，pH 5.0）（54:36:10，v/v/v）和反向固定相。在验证过程中对该方法的特异性、线性、精密度、准确性和稳健性进行了评估和确认。此外，经验证的方法能够测定HYP在NLC中的包封效率。结论：高效液相色谱法得到了验证，结果表明NLC具有递送HYP化合物的能力，可作为食品补充剂进一步应用。亮点：HYP被用作食品补充剂和光动力疗法（PDT）。所开发的方法具有特异性、线性、精确性、准确性和稳健性。NLCs表现出很高的封装HYP的能力。
