“…The available literatures regarding nanoemulsion show that nanoencapsulation results in increasing the overall antioxidant activity. For example; the natural phenolic compound curcumin, resveratrol, Achyrocline satureioides extract and grape extract, were among those which have improved their activity after emulsion with lipid‐based nanostructures (Coradini et al, ; Spigno et al, ; Zorzi, Caregnato, Moreira, Teixeira, & Carvalho, ).…”

Turmeric extract‐based nanoemulsion (TEBN) was prepared using rice bran oil by ultrasonication with Tween 80 as an emulsifier. The effect of different process variables (pH, ultrasonic temperature, and ionic strength) on the selected responses (particle size and zeta potential) of TEBN was analyzed by response surface methodology using central composite design. The regression analysis indicated that the pH, temperature, and ionic strength had a significant effect on the selected responses. The optimized TEBN has particle size of 19.97 nm and zeta potential of −13.10 mV under the optimal conditions (65°C ultrasonic temperature, 0.1 M ionic strength, and 6.5 pH). The optimized antioxidant‐ and antibacterial‐rich nanoemulsion was then studied for its effect on the total viable count, fat content, and peroxide value of Pangas (Pangasianodon hypophthalmus) fillets stored at 20 ± 1°C TEBN‐treated fish fillets showed a significant reduction (p < 0.05) in peroxide value and total viable count. Practical applications In the tropical countries, fishes are usually prone to microbial infestation beyond 20°C temperature. Application of turmeric extract‐based nanoemulsion (TEBN) can be an alternative method for preservation by refrigeration and use of chemical preservatives. Optimized TEBN could increase the shelf life of the Pangas (P. hypophthalmus) fish fillets upto 72 hrs under non‐refrigerated condition.

“…These liposomes were able to increase membrane potential after H 2 O 2 damage and decrease apoptosis. The use for food product is also interesting once grape marc extract, for example, was successfully associated to nanoemulsion and helped to reduce the oxidation of hazelnut paste (Spigno et al, 2013).…”

In many cases, from a pharmacological point of view, it is interesting to work with crude extract or fractions instead of a single isolated compound. This could be due to multi-targeting effect of the extract, lack of knowledge of the active compounds, synergistic effect of the extract compounds, among others. In any case, in order to achieve a final product some issues must be overcome, including poor stability, solvent toxicity, and low solubility of the bioactive compound. Recently many nanotechnology-based strategies have been proposed as an alternative to solve these problems, especially liposomes, nanoemulsions and nanoparticles. In this sense, the present work aims to review the main nanotechnological approaches used for association of different plant extracts and the main achievements form using these technologies.

“…The increase of antioxidant effect after nanoencapsulation has been previously reported by some authors. The natural compounds curcumin and resveratrol, as well as grape extract, are among those which had their activity improved after association to lipid-based nanostructures (48,49). The explanation may rely on the kinetic release of the antioxidants from the oil core.…”

Antioxidant Effect of Nanoemulsions Containing Extract of Achyrocline satureioides (Lam) D.C.—Asteraceae

Abstract. Ethanolic extracts of Achyrocline satureioides have pronounced antioxidant activity mainly due to the presence of the flavonoid quercetin. However, direct topical application of the extract is not possible due to the presence of high amounts of ethanol. In this sense, nanoemulsions arise as an alternative for topical formulation associating molecules with limited aqueous solubility. This article describes the development of topical nanoemulsions containing either A. satureioides extract or one of its most abundant flavonoid, quercetin. Nanoemulsions composed of octyldodecanol, egg lecithin, water and extract (NEE), or quercetin (NEQ) were prepared by spontaneous emulsification. This process led to monodisperse nanoemulsions presenting a mean droplet size of approximately 200-300 nm, negative zeta potential, and high association efficiency. A study of quercetin skin retention using porcine skin which was performed using a Franz diffusion cell revealed a higher accumulation of quercetin in skin for NEE when compared to NEQ. Finally, the antioxidant activity of formulations was measured by thiobarbituric acidreactive species and the APPH model. A lower lipoperoxidation for the extract in respect to quercetin solution was observed. However, no difference between NEQ and NEE lipoperoxidation could be seen. The protection against lipoperoxidation by the formulations was also measured in the skin, where lower formation of reactive species was observed after treatment with NEE. In conclusion, this study shows the formulation effect on the physicochemical properties of nanoemulsions as well as on the skin retention and antioxidant activity of quercetin.
