“…Figure 2 showed also that the antioxidant activity of the extract obtained by UAE is lower than the CSE extract (29.27%). This result is similar to that reported by Dahmoune et al [45] . The authors have shown that the antioxidant activity of the extract of lemon peel obtained by CSE is higher than that achieved by the UAE.…”

The effect of conventional solvent extraction, CSE, ultrasound assisted extraction, UAE, microwave assisted extraction, MAE and supercritical CO 2 extraction, SC-CO 2 on the total phenols content, total flavonoids, individual flavonoids and antioxidant activity of orange peel were compared. Neohesperidin (from 0.624 ± 0.013 for SC-CO 2 extraction to 1.045 ± 0.001 g100 g orange peel powder for MAE) and hesperidin (from 0.407 ± 0.008 for SC-CO 2 extraction to 0.836 ± 0.029 g/100 g orange peel powder for UAE) are the major flavonoids (80% of total flavonoids by MAE and 87% by CSE) of orange peel whatever the used extraction method. The method giving the highest total phenol and flavonoid contents is microwave assisted extraction (2.363 ± 0.014 g GAE/100g orange peel powder), followed by ultrasound assisted extraction, conventional solvent extraction, and supercritical CO 2 extraction. However, antioxidant activity (DPPH method) cannot be correlated to TPC, TFC or individual flavonoids. Orange peel extracted by CSE (ethanol (80%), m/v: 5 g:50 ml, 30 min, 35°C, mechanical stirring at darkness, 3 successive extractions) presents the higher radical scavenging capacity compared to the other extracts obtained by MAE (Ethanol (80%), m/v: 5 g: 50 ml, 10s, 35°C, 170 W, 3 successive extractions) and UAE (ethanol (80%), m/v: 5g:50 ml, 30 min, 35°C, magnetic stirring at darkness, 3 successive extractions, 125W), SC-CO 2 extraction (ethanol (80%), m/v:5 g:50 ml, 30 min, 35°C, 22 MPa, 3 successive extractions). Besides, no additivity on the antioxidant activity is found with the DPPH method.

The effect of four extraction methods applied at 35°C (conventional solvent extraction, CSE, ultrasound assisted extraction, UAE, microwave assisted extraction, MAE and supercritical CO2 extraction, SC-CO2) on the total phenol contents, total flavonoid contents, individual flavonoids, vitamin C and antioxidant activity of orange peel was examined. Neohesperidin (from 0.624±0.013 for SC-CO2 extraction to 1.045±0.001g/100g orange peel powder for MAE) and hesperidin (from 0.407±0.008 for SC-CO2 extraction to 0.836±0.029g/100g orange peel powder for UAE) are the major flavonoids (80% of total flavonoids by MAE and 87% by CSE) of orange peel whatever the used extraction method. The method giving the highest total phenol and flavonoid contents is microwave assisted extraction (2.363±0.014 g GAE/100g orange peel powder), followed by ultrasound assisted extraction, conventional solvent extraction, and supercritical CO2 extraction. However, vitamin C content is not affected by the extraction method. Antioxidant activity (DPPH method) cannot be correlated to TPC, TFC or individual flavonoids. Orange peel extracted by CSE presents the highest radical scavenging capacity compared to the other extracts obtained by MAE, UAE and SC-CO2 extraction. Besides, no additivity on the antioxidant activity is found with the DPPH method.

“…The growing industrialization of agro-food products, especially those from vegetable sources, generate by-products such as peels, bagasse and/or seeds which are considered as agro-industrial residues that can constitute 20% to 50% of the total weight of the plant material [64,67,68]. The lack of final disposal and the inadequate management of these residues has promoted the search for a use for them and, as such, has given them an added value through the extraction of bioactive phytochemicals [25].…”

Vegetable sources and agro-industrial residues represent an important source of phenolic compounds that are useful in a wide range of applications, especially those with biological activities. Conventional techniques of phytochemical extraction have been associated with a high consumption of organic solvents that limits the application of bioactive extracts, leading to the implementation of novel extraction technologies using mechanisms such as Ultrasound Assisted Extraction (UAE). In the present review, an analysis of the involved variables in the extraction yield of phenolic compounds through UAE is presented, highlighting the advantages of this technology based on the results obtained in various optimized studies. A comparison with other technologies and a proposal of its possible application for agro industrial residues as raw material of phenolic compounds is also indicated. Finally, it is concluded that UAE is a technology that is placed within the area of Sustainable Chemistry since it promotes the use of renewable raw materials through the extraction of phenolic compounds, implementing the substitution of organic solvents with solvents that do not present toxic effects, lowering the energy consumption when compared to conventional methods and minimizing process times and temperatures, which is useful for the extraction of thermo-labile compounds.
