“…The extraction with supercritical carbon dioxide was used to acquire extracts from over 300 plant species [19]. This technique has already been used to isolate health-promoting compounds from the pomace of a few plants, inter alia, grapes [20], tomatoes [21], olives [22], sour cherries [14], and the guelder-rose [23].…”

Chokeberry (Aronia melanocarpa (Michx.) Elliot) is a fruit with exceptionally high levels of phenolic compounds which are accumulated mainly in the peel; hence, the majority remains in the leftovers after juice production. Extraction with the use of carbon dioxide in supercritical conditions was used to isolate phenolic compounds from the pomace. The effect of the process parameters (temperature; pressure; and the addition of ethanol) on the extraction yields and properties of the extracts was investigated. The anthocyanin and total phenolic compound content, as well as the scavenging activity against five selected radicals, were evaluated. The best results were acquired for 35 • C, 10 MPa, and 80% m/m ethanol addition, the yield of phenolic compounds was 1.52 g per 100 g of pomace. The amount of extracted phenolics and the antioxidative attributes of the extracts were highly correlated. The impact of supercritical carbon dioxide density on the amount of recovered compounds was confirmed. The use of supercritical CO 2 led to a significant reduction in the volume of organic solvent required for extraction.

“…Extraction of vegetable matrices with supercritical fluids is probably the most classical and well established application of supercritical fluid technology. Carbon dioxide is the most commonly used supercritical solvent in the extraction of flavor and fragrance compounds due to its well-known properties (Reverchon 1997;Reverchon and de Marco 2006;Melo et al 2014). Nevertheless, propane and n-butane can also be a good choice because their critical pressures are relatively low compared to that of carbon dioxide and present a dielectric constant of around 1.7, which is quite similar to carbon dioxide, 1.6 (Weast et al 1988).…”

Phytochemical profile, antioxidant and antimicrobial activity of extracts obtained from erva-mate (Ilex paraguariensis) fruit using compressed propane and supercritical CO2

Traditionally, Ilex paraguariensis leaves are consumed in tea form or as typical drinks like mate and terere, while the fruits are discarded processing and has no commercial value. The aim of this work to evaluate phytochemical properties, total phenolic compounds, antioxidant and antimicrobial activity of extracts of Ilex paraguariensis fruits obtained from supercritical CO 2 and compressed propane extraction. The extraction with compressed propane yielded 2.72 wt%, whereas with supercritical CO 2 1.51 wt% was obtained. The compound extracted in larger amount by the two extraction solvents was caffeine, 163.28 and 54.17 mg/g by supercritical CO 2 and pressurized propane, respectively. The antioxidant activity was more pronounced for the supercritical CO 2 extract, with no difference found in terms of minimum inhibitory concentration for Staphylococcus aureus for the two extracts and better results observed for Escherichia coli when using supercritical CO 2 .

“…Based on the analysis of results published in worldwide scientific literature in 2000 -2013, Melo et al [44] presented an interesting publication concerning the current state of knowledge and research on supercritical extraction of vegetable materials. It includes the analysis of the used plants and obtained products, processing conditions under which they were obtained, including solvents and co-solvents (modifiers), optimization and modelling methods, as well development level of individual processes in terms of their industrial use.…”

“…The above-mentioned publication describes more than 300 raw materials, 28% of the works relates to the extraction of seeds, 17 % -leaves, 10 % -fruit, 7 % -roots, 5 % -flowers, 3 % -rhizome and 32 % -other materials, including their mixtures [44]. SFE extracts obtained from vegetable matrices are typically mixtures of the following compounds: triglycerides, fatty acids, fatty alcohols, terpenoids, phytosterols, tocopherols, tocotrienols and phenolics [44].…”
