“…In the present study, temperature of 60°C promoted better extraction of TPC and SS. This result was also observed in the UAE of active compounds (He et al., 2016, Zhang, Tang, Zheng, Li, & Pan, 2019, Machado et al., 2019, Arteaga‐Crespo, Radice, Bravo‐Sanchez, García‐Quintana, & Scalvenzi, 2020) and soluble sugars (Ramón et al., 2015).…”

“…The efficiency of ultrasound‐assisted extraction (UAE) to the removal of phenolic compounds from food materials was reported in various works, such as: mandarin peel (Nipornram, Tochampa, Rattanatraiwong, & Singanusong, 2018), black and purple rice bran (Das, Goud, & Das, 2017), pomegranate peel (Machado et al., 2019; Sharayei, Azarpazhooh, Zomorodi, & Ramaswamy, 2019), teff grains (Viell et al., 2020), and Brazilian hop (Almeida et al, 2019). At same time, UAE efficacy in the extraction of soluble sugars was observed for defatted soybean flakes (Karki et al, 2010), banana (Rayo‐Mendez, Gómez, & Tadini, 2019), and artichoke biomass (Polachini, Mulet, Telis‐Romero, & Cárcel, 2019).…”

The aim of this work was to investigate the ultrasound‐assisted extraction (UAE) of total phenolic compounds (TPC) and soluble sugars (SS) from the by‐product of peach palm (stem portion). The effect of the processing variables temperature (30–60°C), time (15–45 min), and power density (8.47–25.42 mW cm−3) were evaluated. The maximum contents (dry basis) of TPC (345.81 ± 2.82 mg gallic acid equivalent 100 g−1) and SS (16.68 ± 0.24 g 100 g−1) were obtained, respectively, at 60°C, 30 min and 8.47 mW cm−3 (condition 1) and 60°C, 45 min and 25.42 mW cm−3; in these conditions, the extracts had higher sucrose content than glucose and fructose. The highest content of phenolic acids (gallic, coumaric, vanillic, ferulic, trans‐cinnamic) and highest antioxidant activity were obtained in the condition 1. UAE can be considered an effective method for the extraction of TPC and SS from peach palm stem. Practical applications The ultrasound‐assisted extraction (UAE) was applied in the by‐product of heart‐of‐palm (stem portion) to the removal of phenolic compounds and soluble sugars. To realize this process with time and energy economy, the maximized condition of extraction observed at 60°C, 30 min, and 8.47 mW cm−3 was the most interesting. This extract showed the highest content of phenolic compounds and highest antioxidant potential, which can allow its application to preserve the shelf life of food products or to produce food supplements. The soluble sugars extracted can also be used, as example, in fermentative process. Therefore, the results indicate the viability of UAE to offer alternatives to utilization of stem portion of peach palm.

“…The frequency used for the extraction of bioactive compounds from natural products usually ranges between 20 and 120 kHz. There are some reports that frequency can modulate the removal of different compounds from the sample matrix (Machado et al, 2019 ). In the case of phenolics from grapes lower frequency of 40 kHz provided higher yields than 120 kHz (González-Centeno et al, 2014 ).…”

“…However, very large amplitudes can also lead to the rapid deterioration of the ultrasonic transducer, leading to liquid agitation and not to the cavitation phenomenon. Thus, attention should be paid to the amplitude, especially considering the solvent, where high amplitudes are suitable in more viscous solvents such as the oils (Tiwari, 2015 ; Machado et al, 2019 ).…”

Flavonoids are one of the main groups of polyphenols found in natural products. Traditional flavonoid extraction techniques are being replaced by advanced techniques to reduce energy and solvent consumption, increase efficiency and selectivity, to meet increased market demand and environmental regulations. Advanced technologies, such as microwaves, ultrasound, pressurized liquids, supercritical fluids, and electric fields, are alternatives currently being used. These modern techniques are generally faster, more environmentally friendly, and with higher automation levels compared to conventional extraction techniques. This review will discuss the different methods available for flavonoid extraction from natural sources and the main parameters involved (temperature, solvent, sample quantity, extraction time, among others). Recent trends and their industrial importance are also discussed in detail, providing insight into their potential. Thus, this paper seeks to review the innovations of compound extraction techniques, presenting in each of them their advantages and disadvantages, trying to offer a broader scope in the understanding of flavonoid extraction from different plant matrices.

“…In addition, the low temperature and the short extraction time of UAE can avoid the degradation of anthocyanins caused by high temperature, which contributes to the improvement of the anthocyanin yield [ 10 ]. Thus, the UAE method is used in the extraction of bioactive compounds from different natural plant sources [ 11 , 12 , 13 ]. The combination of UAE and DESs extraction methods has the advantages of both methods, thereby providing effective and environmentally friendly alternatives to the traditional anthocyanin extraction methods.…”

Raspberries have been reported to contain abundant anthocyanins and other active compounds. To extract anthocyanins from raspberries more efficiently, a novel procedure of ultrasound-assisted deep eutectic solvent extraction (UADESE) was proposed in this paper. The extraction process was optimized by response surface methodology coupled with a genetic algorithm. The optimum extraction parameters to achieve the highest yield of anthocyanins 1.378 ± 0.009 mg/g from raspberry powder via UADESE were obtained at a water content of 29%, ultrasonic power of 210 W, extraction temperature of 51 °C and extraction time of 32 min. The AB-8 macroporous resin combined with the high-speed counter current chromatography (HSCCC) method were further used to isolate and purify the anthocyanins extracts obtained under optimum extraction conditions, and the structure of purified anthocyanins components were identified by UV-Visible spectrophotometer (UV-Vis), high-performance liquid chromatography (HPLC), high-performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS/MS), 1H nuclear magnetic resonance (NMR) and 13C-NMR spectra. The two anthocyanins (cyanidin-3-glucoside with a purity of 92.25% and cyanidin-3-rutinoside with a purity of 93.07%) identified were consistent with those present in raspberries. These findings provided an effective and feasible method for extraction, isolation and purification of anthocyanins from natural plant resources.
