For improving quality control in the fermented tea production process and advancing the corresponding food labeling with function claims, a rapid and robust hesperidin analysis method using LC-MS/MS with the sample dilution approach was developed by following internationally accepted criteria of the Association of Official Analytical Chemists (AOAC). The linear correlation coefficient (r 2 ) of the regression line was 0.9997 in the concentration range of 0.025 -2.5 mg/L. The matrix effect evaluated using regression line slope values was negligible. The recovery rate of 100.7% indicated improved trueness. The performance of the newly developed method in determining the hesperidin content of fermented tea samples did not significantly vary from that of a well-established, conventional method. The HorRat values of intra-and inter-laboratory reproducibility studies were both within the acceptable range, indicating sufficient accuracy of the newly developed method according to the AOAC criteria.

“…For benefits of each frequency range for classes of compounds or applications, past literatures have evaluated the ultrasound frequency that delivers high targeted components recovery yields during ultrasound-assisted extraction from natural materials [15][16][17][18]19,20], notably studies on UAE of rutin from different natural materials [7,21]. However, those ultrasound frequencies were empirically selected from ultrasonic apparatuses or devices.…”

A new method has been proposed for enhancing extraction yield of rutin from Sophora japonica, in which a novel ultrasonic extraction system has been developed to perform the determination of optimum ultrasonic frequency by a two-step procedure. This study has systematically investigated the influence of a continuous frequency range of 20-92 kHz on rutin yields. The effects of different operating conditions on rutin yields have also been studied in detail such as solvent concentration, solvent to solid ratio, ultrasound power, temperature and particle size. A higher extraction yield was obtained at the ultrasonic frequency of 60-62 kHz which was little affected under other extraction conditions. Comparative studies between existing methods and the present method were done to verify the effectiveness of this method. Results indicated that the new extraction method gave a higher extraction yield compared with existing ultrasound-assisted extraction (UAE) and soxhlet extraction (SE). Thus, the potential use of this method may be promising for extraction of natural materials on an industrial scale in the future.

“…The results suggested that the frequency of 55 kHz was an optimal ultrasonic frequency for the extraction of glycyrrhizic acid. Similarly, our previous studies [34,35] also reported that the highest extraction yield was obtained at an optimal ultrasonic frequency during the extraction of rutin from Sophora japonica and hesperidin from tangerine peels. These results were mainly attributed to the resonance mechanism of cavitation bubbles generated by ultrasound.…”

“…Secondly, the effect of ultrasonic frequency on the extraction yield of glycyrrhizic acid was performed at 25 • C, and ultrasound power of 125 W with different frequencies (20,30,40,55, and 90 kHz). Finally, the effect of extraction temperature on the extraction yield of glycyrrhizic acid was carried out at an ultrasonic frequency of 55 kHz and power of 125 W with different extraction temperatures (20,25,35,60, and 70 • C). The extraction process was repeated three times for each experiment.…”

This work focused on the intensification of extraction process of glycyrrhizic acid (GA) from Glycyrrhiza uralensis using ultrasound-assisted extraction (UAE) method. Various process parameters such as ultrasonic power, ultrasonic frequency, extraction temperature, and extraction time which affect the extraction yield were optimized. The results showed that all process parameters had exhibited significant influences on the GA extraction. The highest GA yield of 217.7 mg/g was obtained at optimized parameters of 125 W, 55 kHz, 25 • C, and 10 min. Furthermore, the extraction kinetics model of this process was also investigated based on Fick's first law available in the literature. Kinetic parameters such as equilibrium concentration (C e ) and integrated influence coefficient (λ) for different ultrasonic powers, ultrasonic frequencies, and extraction temperatures were predicted. Model validations were done successfully with the average of relative deviation between 0.96% and 4.36% by plotting experimental and predicted values of concentration of GA in extract. This indicated that the developed extraction model could reflect the effectiveness of the extraction of GA from Glycyrrhiza uralensis and therefore serve as the guide for comprehending other UAE process.
