“…All reagents were prepared according to Ding, Jiang, et al. (2019) with some modifications. FRAP reagent was prepared by adding 25 ml of 300 mM acetate buffer (pH 3.6) with 2.5 ml of 10 mM 2,4,6‐tripyridyl‐S‐triazine (TPTZ) solution (in 40 mM HCl) and 2.5 ml of 20 mM FeCl 3 .6H 2 O solution.…”

This study was aimed to enhance the extraction yield of propolis samples using ultrasound technology, analyze the volatile compounds, and compare the antioxidant and antimicrobial effect of propolis extracts of different areas. Four propolis samples were collected from different regions of China, namely: Linqing, Shandong Province (LSP); Yingchun, Heilongjiang Province (YHP); Changge, Henan Province (CHP); and Raohe, Heilongjiang Province (RHP). The ultrasound extracts of CHP and RHP showed a higher total phenolic content (TPC) of 201.78 ± 4.60 mgGAE/g and 166.071 ± 1.53 mgGAE/g, total flavonoid content (TFC) of 519.77 ± 29.90 and 341.227 ± 10.82 mg quercetin/g respectively, as well as high antioxidant and antibacterial activity. Conventional extraction showed 15%–20% lower yield for TPC ranging from 72.02 ± 1.99 to 155.95 ± 3.69 mg GAE/g, TFC ranges from 129.675 ± 6.82 to 412.83 ± 12.14 mg quercetin/g, with lower antibacterial activity. The antioxidant activity of propolis extracts was determined by assays of reducing power, DPPH*, FRAP*, TEAC*, hydroxyl radical scavenging activity and superoxide anion scavenging activity. Collectively, the antioxidant activities of extracts from CHP and RHP were higher than those of the other two extracts(YHP and LSP). All the extracts showed high antimicrobial activity on Staphylococcus aureus, Listeria monocytogenes, and Bacillus subtilis, but no effect on Escherichia coli. A total of 150 compounds in propolis were detected by GC/MS. Terpenes (RHP 34%, YHP 5%, LSP 18%, and CHP 12%) and alcohols (RHP 12%, YHP 13%, LSP 12%, and CHP 10%) showed the highest relative content among all other extracts.

“…Nitrogen is an inert gas that could replace atmospheric oxygen in the extraction system and interrupt oxygen‐induced oxidation to protect plant polyphenols. From the sustainability point of view, it is also worth mentioning that the nitrogen could be recycled during the extraction process and reused for further extractions (Ding et al ., 2019). Similar results in the extraction of polyphenols were also observed in other Mediterranean plants such as rosemary and wild thyme (Nutrizio et al ., 2020a,c).…”

Summary The aim of the study was to observe the sustainability parameters of high voltage electrical discharge (HVED) as a novel technology for extraction of phenolic compounds from oregano. The life cycle assessment (LCA) of HVED was evaluated and compared with conventional extraction methods–infusion and maceration. The results showed that HVED extraction with nitrogen gave 2.19%–34.04% higher yield of phenolic compounds compared to infusion and 6.13%–90.95% higher yield compared to maceration, depending on the voltage and treatment time used for HVED. The environmental pillar of LCA, assessed by global warming potential, ranged from 1.130 to 4.635 kg CO2e for HVED samples treated with nitrogen and from 1.207 to 4.487 kg CO2e for samples treated with argon, which was mainly related to the duration of treatment. Other pillars of sustainability, namely society, economy, food safety and quality, were discussed. HVED was found to be the more sustainable technology (based on the results from LCA), with prospects for future scale‐up for the food industry.

“…Ultrasonic technology has been widely applied in the research field of natural plant extraction. Ding et al [60] found that ultrasonic extraction could significantly improve the extraction rate of polyphenols from rapeseed meals, but it would cause a series of oxidation reactions that might reduce the antioxidant properties of polyphenols. Therefore, nitrogen protection was necessary to assist the extraction.…”
