Abstract

Abstract Functional foods, drug delivery systems, and cosmetics are the main areas of application for multiphase systems, where the use of naturally derived compounds is preferred. Hence, this study aimed to assess the possibility of using natural surfactants and saponin-rich extracts to produce emulsions containing antibacterial and antioxidant cinnamon and clove essential oils (EOs). The analyses of nanoparticles using dynamic light scattering showed that the addition of plant extracts to solutions allows one to obtain stable emulsions and decreased zeta potential (< −40 mV) and droplet size (<200 nm). In all investigated emulsions, the increase of antioxidative properties was observed when both EOs and plant extracts were used. The emulsion with clove oil stabilized with Quillaja saponaria bark saponins has the highest combined antioxidative properties (3.55 ± 0.01 μg gallic acid equivalent per g). Additionally, a stronger antibacterial action against Pseudomonas bacteria was observed for clove oil with Quillaja saponaria and cinnamon oil with Glycyrrhiza glabra. In addition, plant extracts did not affect significantly the other properties of the oil emulsions, e.g. wettability, colour, and refractive index. All results show that the proposed emulsions can be helpful in the preparation of multifunctional emulsions, where the co-action of saponins and EOs is especially beneficial.
用皂素稳定的精油纳米乳具有抗菌和抗氧化的特性
功能食品、药物输送系统和化妆品是多相系统的主要应用领域,在这些领域中,天然衍生化合物的使用是首选的。因此,本研究旨在评估使用天然表面活性剂和富含皂苷的提取物生产含有抗菌和抗氧化肉桂丁香精油(EOs)的乳剂的可能性。利用动态光散射对纳米颗粒进行分析表明,在溶液中加入植物提取物可以获得稳定的乳液,并且可以降低zeta电位(< - 40 mV)和液滴尺寸(<200 nm)。在所有研究的乳剂中,当使用EOs和植物提取物时,观察到抗氧化性能的增加。以黄芪皮皂苷稳定的丁香油乳液的综合抗氧化性能最高(3.55±0.01 μg没食子酸当量/ g),且黄芪皮油和甘草肉桂油对假单胞菌的抑菌作用较强。此外,植物提取物对油乳剂的其他性质,如润湿性、颜色和折射率没有显著影响。结果表明,该乳剂可用于制备多功能乳剂,其中皂苷与EOs的协同作用尤为有利。
