Saponin was extracted from the Anabasis setifera plant and used to stabilize an oil-in-water (O/W) emulsion based on date palm kernel oil. Different amounts of the extracted saponin were used with a constant oil concentration (1.5% w/w). The droplet size distribution, emulsion droplet size value (d-ave), polydispersity index (PDI) and zeta potential of the emulsions were determined using dynamic light scattering (DLS). These parameters were measured and compared after seven days of emulsion preparation. The best results (d-ave = 41.7 nm, PDI = 0.1 and zeta potential = −29.8 mV) were obtained for the CMC of saponin. Both the oil and the surfactant were specifically extracted and used from the nature of Saravan in the Baluchestan region of Iran. This research presents a green and cost-effective aspect for potential formulations of nano-emulsions that can be used in the food and cosmetic industries.

从红枣植物中提取的皂苷作为生物表面活性剂用于稳定基于海枣（Phoenix dactylifera）仁油的水包油（O/W）纳米乳液

皂甙提取自鱼腥藻植物并用于稳定基于椰枣仁油的水包油 (O/W) 乳液。在恒定油浓度 (1.5% w/w) 下使用不同量的提取皂苷。液滴粒径分布、乳液液滴粒径值（d-ave)、多分散指数 (PDI) 和乳液的 zeta 电位使用动态光散射 (DLS) 测定。在乳液制备 7 天后测量和比较这些参数。最好的结果（d-ave = 41.7 nm, PDI = 0.1 和 zeta 电位 = -29.8 mV) 用于皂苷的 CMC。油和表面活性剂都是从伊朗俾路支斯坦地区的 Saravan 自然中专门提取和使用的。这项研究为可用于食品和化妆品行业的纳米乳液的潜在配方提出了绿色和成本效益的方面。
