“…The maximum yield of polysaccharide (11.64%) was detected at 70℃ which a sharp declined as soon at the temperature attained 80℃. Although, some studies had suggested that a higher temperature benefit the solubility and extraction yield of polysaccharide [35] but when the temperature was above certain degree, it could decrease the polysaccharide yield of some plant materials as shown in Figure 2b. So, the temperature range of 60-80℃ was adopted as the optimal for the BBD experiment.…”

Leonurus japonicus is rich in bioactive compounds especially polysaccharide. Single factors test and response surface methodology were used to study the optimum conditions for ultrasonic - assisted extraction of polysaccharide from L. japonicus, and its physiochemical and DPPH scavenging activities also were evaluated. The optimal conditions as underpinned by this paper is as follow: extraction temperature of 70 �C, extraction time of 50 min and extraction power of 210W. The polysaccharide of L. japonicus was shown to be a non-reducing sugar and to exhibit DPPH scavenging activity to an extent. The polysaccharide structures were studied using SEM, AFM, and FT-IR. It showed L. japonicus polysaccharide had been having more than one chains which were branched and entangled with each other. and existed a broad band wavelength of 2925.64, 1635.06, 1539.7, 1046.73, and 477.86 cm-1. The study indicated that L. japonicus may have a beneficial use to the medical and food industries.

“…Finally, although the energy that was provided by ultrasound is necessary to release the compounds from the matrix, it may also accelerate the degradation process of the phenolic compounds [54]. In general, the action of the ultrasounds would increase the solubility of the molecules by destroying the intramolecular and intermolecular bonds and by increasing the contact between the hydrophilic groups and the extraction solvents [55]. Although it is clear that the cycle also presents an extreme value, its modification was not considered, since it was not an influential variable.…”

Assessment of Ultrasound Assisted Extraction as an Alternative Method for the Extraction of Anthocyanins and Total Phenolic Compounds from Maqui Berries (Aristotelia chilensis (Mol.) Stuntz)

et al. 2019

Research interest regarding maqui (Aristotelia chilensis) has increased over the last years due to its potential health benefits as one of the most antioxidant-rich berries. Ultrasound-assisted extraction (UAE) is an advanced green, fast, and ecological extraction technique for the production of high quality extracts from natural products, so it has been proposed in this work as an ideal alternative extraction technique for obtaining extracts of high bioactivity from maqui berries. In order to determine the optimal conditions, the extraction variables (percentage of methanol, pH, temperature, ratio “sample mass/volume of solvent”, amplitude, and cycle) were analyzed by a Box-Behnken design, in conjunction with the response surface method. The statistical analysis revealed that the temperature and the percentage of methanol were the most influential variables on the extraction of the total phenolic compounds and total anthocyanins, respectively. The optimal extraction time was determined at 15 min for total phenolic compounds, while it was only 5 min for anthocyanins. The developed methods showed a high precision level with a coefficient of variation of less than 5%. Finally, the new methods were successfully applied to several real samples. Subsequently, the results were compared to those that were obtained in previous experiments by means of microwave assisted extraction (MAE). Similar extraction yields were obtained for phenolic compounds under optimized conditions. However, UAE proved to be slightly more efficient than MAE in the extraction of anthocyanins.

The study investigated the effect of dual‐frequency ultrasound‐assisted alcohol/salt aqueous two‐phase extraction and desalination on the yield, microstructure and antioxidant properties of Astragalus polysaccharides (APS). Extracts were desalinated for 10 (APS10), 20 (APS20), and 30 (APS30) minutes. A 28.40% experimental yield, well correlated to the response surface methodology predicted model was achieved. Thermodynamic parameters were non‐spontaneous, irreversible and endothermic. Moreover, ultrasound enhanced the desalination rate and did not alter the chemical structure in the APS. Fourier Transform Infrared Spectroscopy showed a similar spectrum in all the APS samples. High‐performance gel chromatography and scanning electron microscopy, respectively presented reduced molecular weights and altered microstructures in the samples. Monosaccharide analysis revealed the existence of xylose, mannose, galactose, glucose, arabinose, rhamnose, and ribose in the APS samples. Moreover, the APS20 showed strong hydroxyl and 2,2‐diphenyl‐1‐picrylhydrazyl radical scavenging activities, thus showing its potency in reducing oxidative stress. Hence, this study demonstrates that coupled ultrasound and alcohol/salt ATPS is a sustainable technique, which generates high yields of simultaneously extracted products. Practical applications Astragalus root has been used as an effective complementary treatment to conventional medicine owing to its rich nutraceutical composition and its numerous health attributes. Commercialization of Astragalus supplements into functional foods and nutraceuticals requires continuous exploration of novel, low cost and reproducible methods that retain their bioactivity. In this work, a synergized and bio‐compatible dual‐frequency ultrasound‐assisted alcohol/salt aqueous two‐phase system was used to extract and purify Astragalus polysaccharides. Application of this technique in the nutraceutical industry reduces treatment time, lowers bulk energy consumption hence reducing energy costs. It promotes the use of low‐cost, non‐hazardous bio‐based solvents in treatment processes thus considerably reducing extraction costs and environmental degradation. Findings from this study exhibit the practicability of this technique in industrial application. It equips biotechnologists with information on improved, sustainable and safer ways of extracting and enriching the quality of nutraceutical compounds.
