“…Oliveira et al (2013) using grape extract obtained with supercritical CO 2 , noted a moderate inhibitory effect against Staphylococcus aureus and Escherichia coli. Czaikoski et al (2015) using Eupatorium intermedium flower extracts obtained with supercritical carbon dioxide and pressurized propane, noticed the efficacy against Staphylococcus aureus, whereas Escherichia coli was completely resistant to the extracts.…”

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 .

“…There are many classes of negatively charged polyphenols, identified in grapes, such as phenolic acids (benzoic and hydroxycinnamic acids), stilbene derivatives (Resveratrol), flavan-3-ols (catechin, epicatechin), flavonols (kaempferol, quercetin, myricetin), anthocyanins, etc. (Oliveira et al, 2013). These polyphenols possesses many beneficial effects, on human health such as inhibition of free radical damage, antibacterial, antifungal, decreasing the risk of cardiovascular diseases, anticarcinogenic and anti-inflammatory etc.…”

A diet rich in natural antioxidants appears to be inversely associated with degenerative chronic diseases, such as cardiovascular disease, cancer, obesity, and diabetes, as well as with the prevention of general inflammatory health implications. Grapes (Vitis vinifera) and Dragon fruits (Hylocereus undatus) are important antioxidant rich fruits, belonging to the family Vitaceae and Cactaceae, respectively. In the present study, the aqueous extract of Vitis vinifera and Hylocereus undatus were subjected to GC-MS analysis. The major chemical constituents in both fruits were identified.

Grapes are widely known for health benefits due to their antioxidant content. In wine production, grape stems are often discarded, though they has a higher content of antioxidants than the juice. The effectiveness of using an environmentally friendly solvent, ethanol, as a superheated liquid and supercritical fluid to extract antioxidant compounds from grape stems of organically grown Crimson Seedless grapes was evaluated. The Ferric Reducing Ability of Plasma (FRAP) assay and the Total Phenolic Content (TPC), or Folin‐Ciocalteu assay, were used to quantify the antioxidant power of grape stem extracts. The extractions were performed at temperatures between 160°C and 300°C at constant density. It was found that the optimal extraction temperature was 204°C, at superheated liquid conditions, with a FRAP value of 0.670 mmol Trolox Equivalent/g of dry grape stem. The FRAP values were higher than other studies that extracted antioxidants from grape stems using single‐pass batch extraction.
