“…The HPLC/UV/DPPH• chromatograms of ethanol and water extracts of SBP (negative peaks) revealed the presence of numerous radical scavenging compounds (Figure 3). It may be assumed that proanthocyanidins (6-9), flavan-3-ols (11,14), flavonol glycosides (15,16,(19)(20)(21)(22)(24)(25)(26)(27), flavonols (23,28) terpenoid (5) were the most active radical scavengers in the investigated extracts.…”

This study aimed at valorisation of sea buckthorn pomace (SBP) for the production of extracts containing valuable bioactive compounds. For this purpose, SBP defatted by supercritical CO2 was subjected to consecutive fractionation with pressurized ethanol and water, which yielded 11.9% and 4.8% of extracts, respectively. The extracts were evaluated for their antioxidant potential, phytochemical composition and antiproliferative effects against cancer cells. Water extracts exhibited remarkably higher values in Folin-Ciocalteu assay of total phenolic content, oxygen radical absorbance capacity (ORAC), ABTS●+/DPPH● scavenging and cellular antioxidant activity (CAA) assays and more efficiently inhibited proliferation of HT29 cells at non-cytotoxic concentrations measured in non-tumoral Caco2 cells. Among 28 detected and 21 quantified phytochemicals, flavonols with the structures of isorhamnetin (five compounds), quercetin (three compounds), kaempferol (three compounds) glycosides and catechin (six compounds) were the most abundant in the extracts. In conclusion, the applied method of fractionation of SBP produces promising natural antioxidant complexes with antiproliferative properties that could find potential applications in nutraceuticals, functional foods and cosmeceuticals.

“…The food processing sector contributes the most to food waste—in 2012, this was estimated to be 17 million tons or 19% of a total amount of 87.6 million tons of food waste generated in the EU-28, based on data provided by Fusions EU Project [4]. In large-scale apple juice production, 75% of the apple are utilized for juice, while the remaining 25% are discarded as waste or utilized rather inefficiently [5]. These by-products may be processed and further incorporated as ingredients in making high-value functional food products (cereal bars, cookies, muffins, bread and fermented milk products) with many physiological and biochemical effects [6].…”

The amplified production of fruit as well as burgeoning demand for plant-made food products have resulted in a sharp increase of waste. Currently, millions of tons of by-products are either being discarded or utilized rather ineffectively. However, these by-products may be processed and further incorporated as functional ingredients in making high-value food products with many physiological and biochemical effects. The chemical analysis of pomace oils using gas chromatography-mass spectrometry (GC/MS) and reversed-phase-liquid chromatography coupled with fluorescence detector (RP-HPLC/FLD) systems led to the identification and quantification of 56 individual lipophilic compounds including unsaturated, polyunsaturated and saturated fatty acids, as well as phytosterols and four homologs of tocopherol. The oils recovered from by-products of Malus spp. (particularly cv. “Ola”) are rich in fatty acids such as linolenic (57.8%), α-linolenic (54.3%), and oleic (25.5%). The concentration of total tocopherols varied among the Malus species and dessert apples investigated, representing the range of 16.8–30.9 mg mL−1. The highest content of total tocopherols was found in M. Bernu prieks, followed by M. cv. “Ola”, and M. × Soulardii pomace oils. A significantly higher amount of δ-tocopherol was established in the oil of M. Bernu prieks, indicating that this species could be utilized as a natural and cheap source of bioactive molecules. β-Sitosterol was the prevalent compound determined in all tested pomace oils with a percentage distribution of 10.3–94.5%. The main triterpene identified in the oils was lupeol, which varied in the range of 0.1–66.3%. A targeted utilization of apple pomace would facilitate management of tons of by-products and benefit the environment and industry.

“…Other MAE methods were developed in the absence of a solvent and are usually used for volatile compounds extraction (Kala et al, 2016). SB pomace, seeds, and leaves were used in extraction experiments using supercritical carbon extraction, UAE, MAE, pressurized liquid and enzyme-assisted extraction for obtaining valuables bioactive compounds (Chemat, Périno-Issartier, Loucif, Elmaataoui, & Mason, 2012;Kitrytė et al, 2017;Michel, Destandau, & Elfakir, 2011;Sharma et al, 2008). Both techniques are realistic options also for industrial applications, not only for extraction of active compounds, but also for chemical synthesis and environmental protection (Leonelli & Mason, 2010;Patist & Bates, 2008;Vilkhu, Mawson, Simons, & Bates, 2008).…”

Sea buckthorn (SB) seeds were used as raw material to obtain SB oil using two extraction methods: ultrasound and microwave assisted extraction. The favorable experimental conditions that maximize the extraction efficiency were investigated by applying response surface methodology (RSM). The selected key independent variables were ultrasonic intensity (UI), temperature, and time for ultrasound assisted extraction (UAE) and microwave power, time, and solid/liquid ratio for microwave assisted extraction (MAE). The results obtained for extraction efficiency under optimal conditions are comparable for the two extraction methods (89.2 ± 0.50% for MAE and 87.4 ± 0.44% for UAE). The operation conditions for maximum extraction efficiency were: 13.77 W/cm2 UI, 40 °C temperature, and 10 min extraction time for UAE and 225 W microwave power, 15 ml/ g solid/liquid ratio, and 20 min extraction time for MAE. The extraction kinetics was characterized using a second order model for optimal conditions for UAE and MAE of SB seed oil. Practical applications This article describes two modern methods of sea buckthorn seed oil extraction: ultrasound assisted extraction (UAE) and microwave assisted extraction. Both methods offer many advantages if they are likened with conventional oil extraction. The results illustrated that both methods give comparable values for extraction efficiency, but with an advantage for UAE. The extraction time for UAE is shorter in comparison with MAE (10 min in comparison with 20 min).
