Abstract: 
hesperetin, an abundant bioactive component of citrus fruits, is poorly water-soluble, resulting in low oral bioavailability. We developed new formulations to improve the water solubility, antioxidant activity, and oral absorption of hesperetin. Two nano-based formulations were developed, namely hesperetin-TPGS (D;-tocopheryl polyethylene glycol 1000 succinate) micelles and hesperetin-phosphatidylcholine (PC) complexes. These two formulations were prepared by a simple technique called solvent dispersion, using US Food and Drug Administration (FDA)-approved excipients for drugs. Differential scanning calorimetry (DSC) and dynamic light scattering (DLS) were used to characterize the formulations’ physical properties. Cytotoxicity analysis, cellular antioxidant activity assay, and a pharmacokinetic study were performed to evaluate the biological properties of these two formulations. The final weight ratios of both hesperetin to TPGS and hesperetin to PC were 1:12 based on their water solubility, which increased to 21.5- and 20.7-fold, respectively. The hesperetin-TPGS micelles had a small particle size of 26.19 nm, whereas the hesperetin-PC complexes exhibited a larger particle size of 219.15 nm. In addition, the cellular antioxidant activity assay indicated that both hesperetin-TPGS micelles and hesperetin-PC complexes increased the antioxidant activity of hesperetin to 4.2- and 3.9-fold, respectively. Importantly, the in vivo oral absorption study on rats indicated that the micelles and complexes significantly increased the peak plasma concentration (Cmax) from 2.64 μg/mL to 20.67 and 33.09 μg/mL and also increased the area under the concentration–time curve of hesperetin after oral administration to 16.2- and 18.0-fold, respectively. The micelles and complexes increased the solubility and remarkably improved the in vitro antioxidant activity and in vivo oral absorption of hesperetin, indicating these formulations’ potential applications in drugs and healthcare products.

高水溶性、抗氧化活性和口服吸收率的橙皮素纳米制剂的制备

目的:橙皮素拥有抗氧化、抗炎和降脂等多种生理活性,但由于其水溶性差、代谢快,导致其口服生物利用度很低.因此,本研究制备了橙皮素-维生素E聚乙二醇琥珀酸酯(TPGS)胶束和橙皮素-磷脂酰胆碱(PC)复合物,来提高橙皮素的水溶性、抗氧化活性和口服吸收率.
创新点:本研究使用美国食品药品监督管理局(US FDA)批准的辅料制备了两种纳米制剂:橙皮素-TPGS胶束和橙皮素-PC复合物.不仅制备方法简单,而且能显著提高橙皮素的水溶性、抗氧化活性和口服吸收率.
方法:本研究使用溶剂分散法制备纳米制剂.将橙皮素与分散剂溶于有机溶剂中,在40 °C下搅拌30 min,然后旋转蒸发除去溶剂,用水复溶即得橙皮素-TPGS胶束和橙皮素-PC复合物.本研究使用差示扫描量热法表征纳米制剂的热效应;用动态光散射法测定纳米制剂的粒径;用噻唑蓝(MTT)法检测纳米制剂的细胞毒性;用细胞抗氧化活性测定法对比纳米制剂与橙皮素本身的抗氧化活性;使用灌胃法评估纳米制剂的口服吸收效果.
结论:研究结果发现:以质量比1:12制备的橙皮素-TPGS胶束和橙皮素-PC复合物,其粒径分别为26.19和219.15 nm,没有明显的细胞毒性,同时能够将橙皮素的水溶性分别提高到21.5和20.7倍,抗氧化活性分别提高到4.2和3.9倍,口服生物利用分别提高到16.2和18.0倍.因此,这两种纳米制剂在药剂和保健品制造方面具有重要的应用价值.
